The BrowseNodes tool automatically gets all the child BrowseNodes and their names. The program recursively traverses the BrowserNode hierarchy and returns all the BrowseNodes and their respective names. You can display the nodes on the console or save it to a CSV file. You can also include the library in your existing projects to process BrowseNodes.

Library Usage

The library is easy to use, and requires PHP and CURL installed on your system. The download includes a sample file with which you can immediately test the code. The sample file is shown below.

<?php
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
 
$public_key     = "YOUR-AMAZON-PUBLIC-KEY";
$private_key    = "YOUR-AMAZON-SECRET-KEY";
$region         = "com"; // or "CA" or "DE" etc.
 
$obj = new AmazonProductAPI($public_key, $private_key, $region);
 
/* Display the BrowseNodes to the console */
$obj->setMedia("display");
 
$obj->getBrowseNodes("1266092011");
 
?>

Before you begin to use the library, you need to enter your Amazon security credentials as shown above. Also in the ‘aws_signed_request.php’ file you will need to enter your Amazon Associate ID, as it is now mandatory. Find the following line in the file and add your Associated ID.

/* aws_signed_request.php */
.
.
$params["AssociateTag"]     = 'YOUR-ASSOCIATES-ID-HERE';
.

That is it. Now you are ready to get the BrowserNodes from Amazon. You can display the BrowserNodes on you console/browser or save it directly to a CSV file. For that you have to use the ‘setMedia’ method. Both example are shown below.

Display the BrowseNodes on the console

<?php
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
 
$public_key     = "YOUR-AMAZON-PUBLIC-KEY";
$private_key    = "YOUR-AMAZON-SECRET-KEY";
$region         = "com"; // or "CA" or "DE" etc.
 
$obj = new AmazonProductAPI($public_key, $private_key, $region);
 
/* Display the BrowseNodes to the console */
$obj->setMedia("display");
 
$obj->getBrowseNodes("1266092011");
 
?>

You enter the parent browsenode in the ‘getBrowseNodes’ method, after which the function recursively retrieves all the children nodes. To get started, you can find all the top browsenode values here, or you can get it from the Amazon link itself.

The output of the above is shown below. The output is indented so that you can visualize the hierarchy of the nodes.

Television & Video : AV Receivers & Amplifiers : 3213035011
Television & Video : Blu-ray Players & Recorders : 3213025011
      Blu-ray Players & Recorders : Blu-ray Recorders : 3213026011

The format of each line is given below.

Saving the BrowseNodes to a CSV

The following code shows how to save the browsenodes to a CSV file.

<?php
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
 
$public_key     = "YOUR-AMAZON-PUBLIC-KEY";
$private_key    = "YOUR-AMAZON-SECRET-KEY";
$region         = "com"; // or "CA" or "DE" etc.
 
$obj = new AmazonProductAPI($public_key, $private_key, $region);
 
/* Write the BrowseNodes to a CSV file */
$obj->setMedia("csv", "./nodes.csv");
 
$obj->getBrowseNodes("1266092011");
 
?>

The code saves all the browsenodes in a CSV file, after which you can use it with Excel or a simple text editor. A sample CSV ouput is shown below. The format is the same as the one given above.

"PlayStation 3","All Games","14210861"
"PlayStation 3","Action","14210761"
"Action","Fighting","14210981"
"Action","Military & Espionage","14210821"
"Action","Shooter","14210841"
"PlayStation 3","Adventure","14210851"
"PlayStation 3","Arcade","14210911"
"PlayStation 3","Board Games","14210921"

Changing Locales

Amazon being a world-wide venture the Product Advertising API operates in the following locales:
CA
CN
DE
ES
FR
IT
JP
UK
US

You can use different locale code to get the BrowseNodes for different regions. You set the locale parameter using the ‘$region’ variable; for example:

$region = "com"; // or "CA" or "DE" etc.

Getting the parent node details

You can also get information about a nodes parent node using the ‘getParentNode’ method.

<?php
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
 
$public_key     = "YOUR-AMAZON-PUBLIC-KEY";
$private_key    = "YOUR-AMAZON-SECRET-KEY";
$region         = "com"; // or "CA" or "DE" etc.
 
$obj = new AmazonProductAPI($public_key, $private_key, $region);
 
print_r($obj->getParentNode("14210821"));
 
?>

One other useful method you can use it ‘getNodeName’. This allows you to get the name of a given node id. This can be useful if you have a nodeid but need to gets it name.

<?php
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
 
$public_key     = "YOUR-AMAZON-PUBLIC-KEY";
$private_key    = "YOUR-AMAZON-SECRET-KEY";
$region         = "com"; // or "CA" or "DE" etc.
 
$obj = new AmazonProductAPI($public_key, $private_key, $region);
 
echo $obj->getNodeName("14210821");
 
?>

Note: Some categories contain hundreds to thousands of BrowserNodes, retreiving them can take some time and could trigger a PHP timeout error. To avoid this set PHP timeout to a large number as given below.

<?php
 
set_time_limit(10000); 
 
/* Example usage of the Amazon Product Advertising API */
include("amazon_api_class.php");
.
.
?>

Take a quick example of the ‘pluck’ method.

include_once('underscore.php');
 
$members= array(
  array('name'=>'bill', 'age'=>40, 'gender' => 'm'),
  array('name'=>'john', 'age'=>50, 'gender' => 'm'),
  array('name'=>'sarah','age'=>60, 'gender' => 'f')
);
 
$ret = __::pluck($members, 'name');
print_r($ret);

returns…

Array
(
    [0] => bill
    [1] => john
    [2] => sarah
)

Here is another using the ‘map’ method.

$ret = __::map(array(1, 2, 3), function($num) { return $num * 3; });
print_r($ret);

returns…

Array
(
    [0] => 3
    [1] => 6
    [2] => 9
)

Underscore.php works in both object-oriented and static styles. The following lines give the examples of both.

$members= array(
  array('name'=>'bill', 'age'=>40, 'gender' => 'm'),
  array('name'=>'john', 'age'=>50, 'gender' => 'm'),
  array('name'=>'sarah','age'=>60, 'gender' => 'f')
);
 
/* Static style */
$ret = __::max($members, function($member) { return $member['age']; });
 
/* Object Oriented style */
$ret = __($members)->max(function($member) { return $member['age']; });
 
print_r($ret);

returns…

Array
(
    [name] => sarah
    [age] => 60
    [gender] => f
)

Another example using the ‘template’ method.

$members = array(
  array('name'=>'bill', 'age'=>40, 'gender' => 'm'),
  array('name'=>'john', 'age'=>50, 'gender' => 'm'),
  array('name'=>'sarah','age'=>60, 'gender' => 'f')
);
 
$template = '<% __::each($members, function($member) { 
             %> <li><%= $member["name"] %></li> <% }); %>';
 
$ret = __::template($template, array('members'=>$members));
 
print_r($ret);

returns…

<li>bill</li>  
<li>john</li>  
<li>sarah</li>

How does it work

The underscore.php files defines a ‘__’ class which encapsulates all the functional methods and uses the functional programming ideas introduced in PHP 5.3.

// Underscore.php
 
class __ {
  // Return an array of values by mapping each item through the iterator
  public function map($collection=null, $iterator=null) {
     ...
  }
  .
  .
  /* other methods */
}

Presently the library supports the following methods.

Collections
each, map, reduce, reduceRight, detect, select, reject, all, any, includ, invoke, pluck, max, min, groupBy, sortBy, sortedIndex, toArray, size

Arrays
first, rest, last, compact, flatten, without, uniq, union, intersection, difference, zip, indexOf, lastIndexOf, range

Functions
memoize, throttle, once, after, wrap, compose

Objects
keys, values, functions, extend, defaults, clon, tap, isEqual, isEmpty, isObject, isArray, isFunction, isString, isNumber, isBoolean, isDate, isNaN, isNull

Utility
identity, times, mixin, uniqueId, template

Chaining
chain, value

OPA is concise, simple and readable, it is also provides concurrent, dynamically distributed, and extremely secure programming model. Opa is designed to make web development fun, secure and right. Opa is a complete language and not just a framework, the unified approach of Opa delivers a new level of developing experience with unmatched ease of use and security.

While Opa offers all the features that developers have come to expect from a high-end web server, a high-end distributed database management system, frameworks or distribution engine, Opa does not resemble Apache or Tomcat, MySQL or Oracle SQL, Drupal or Ruby on Rails, Google AppEngine or Hadoop.

Developing with Opa is as simple as it gets: first, you write your code with the Opa programming language — and only the Opa programming language, no JavaScript, no SQL, or anything such (this is something new, will take sometime getting used to). Then compile the code, and let Opa analyze security, generate the code for the browser, for the server, for the database, and combine it with the web server. Finally, launch your executable and your browser. No need to independently deploy, administer or maintain a database management system, a web server, frameworks or middleware. And, of course, the application works on any recent browser, whether mobile or desktop. Oh yes, and it is right away “Cloud-ready”.

Let us take a sneak peek preview and take a look at the simplest application: Hello, web.

server = one_page_server("Hello", -> <>Hello, web!</>)

This is the full source code of the application. Without any setup (besides the installation of the compiler), obtaining a complete, deployable application is only a matter of one step:

opa hello_web.opa

This command produces a stand-alone executable binary, containing everything required for execution, including database management, compiled requests, server code, client code, user interface and everything that may be needed to connect them or to handle malicious connections or inputs. Opa generated and checked all this code for you. You may now launch the server:

./hello_web.exe

Or, if you prefer, you may deploy it to a cloud:

opa-cloud hello_web.exe --host localhost --host my@server1 --host my@server2

Your application is launched, load-balanced, and servers share whichever information is necessary.

Although I’ve yet to develop an OPA application of more than average complexity to gauge the actual benefits of it; it looks promising and also something new to try. The OPA API also looks quite complete and well documented.

Also, it’s not just for images, it also can hold videos and text and it can be used as an endless grid or also as the popular Coda Slider.

The plugin also provides many interesting variations on the basic theme as shown below.

Installing

Before reading further you can download the code below. The original JavaScript port is located here, the following includes the complete code with a crop method added along with a few example files. As the code relies on the GD library, make sure that it is installed and activated on your system.

Running our sample code

The sample code to show the detected face is show below. Note that in images having multiple faces only the first one is detected. Although this might seem like a limitation, this can be useful in web applications that need to create a user profile picture from a raw image. So that if a user uploads a full length picture of him/her, the given code can detect the face and automatically create a profile picture for the user.

<?php
 
include "FaceDetector.php";
 
$face_detect = new Face_Detector('detection.dat');
$face_detect->face_detect('sample-image3.jpg');
$face_detect->toJpeg();
 
?>

Flickr :By modelxing

The above code displays a border around the detected face, instead we can directly crop the resulting face area and output the resulting image.

<?php
 
include "FaceDetector.php";
 
$face_detect = new Face_Detector('detection.dat');
$face_detect->face_detect('sample-image3.jpg');
$face_detect->cropFace();
 
?>

Face coordinates

If you need the coordinates of the detected face for further processing, you can use the following.

// Return coordinates in JSON
// {'x':56.375, 'y':45.1, 'w':227.55}
$face_detect->toJson();
 
// OR
 
// Return coordinates as an Array
$face_detect->getFace();

Extending the class

You can extend the Face_Detector class using your own methods. For example I’ve added three methods – Rotate(), resizeFace() and toGrayScale() to the class, which lets you modify the final face area further.

<?php
 
include "FaceDetector.php";
 
/* We now extend the above class so we can add our own methods */
class FaceModify extends Face_Detector {
 
  public function Rotate() {
    $canvas = imagecreatetruecolor($this->face['w'], $this->face['w']);
    imagecopy($canvas, $this->canvas, 0, 0, $this->face['x'], 
              $this->face['x'], $this->face['w'], $this->face['w']);
    $canvas = imagerotate($canvas, 180, 0);
    $this->_outImage($canvas);
  }
 
  public function toGrayScale() {
    $canvas = imagecreatetruecolor($this->face['w'], $this->face['w']);
    imagecopy($canvas, $this->canvas, 0, 0, $this->face['x'], 
              $this->face['x'], $this->face['w'], $this->face['w']);
    imagefilter ($canvas, IMG_FILTER_GRAYSCALE);
    $this->_outImage($canvas);
  }
 
  public function resizeFace($width, $height) {
    $canvas = imagecreatetruecolor($width, $width);
    imagecopyresized($canvas, $this->canvas, 0, 0, $this->face['x'], 
                     $this->face['y'], $width, $height, 
                     $this->face['w'], $this->face['w']);
    $this->_outImage($canvas);
  }
 
  private function _outImage($canvas) {
    header('Content-type: image/jpeg');
    imagejpeg($canvas);
  }
}
 
 
/* Using the extended class */
$face_detect = new FaceModify('detection.dat');
$face_detect->face_detect('sample-image3.jpg');
$face_detect->resizeFace(100,100);
 
?>

NB: If for some reason the code returns a error, turn off error reporting in php.ini

wkhtmltoimage is a simple shell utility which can be used to convert html to images using the webkit rendering engine, and qt.

Installation

To get started we need to first download and install the shell program wkhtmltoimage. Select the appropriate binaries for your platform. As I’m using Ubuntu 10, I downloaded the complied binary ‘wkhtmltoimage-0.10.0_rc2-static-i386.tar.bz2′. Extract it to a appropriate folder and you are ready to go.

Getting your first snapshot

The simplest way to get a snapshot of a url is through the following:

wkhtmltoimage http://www.bbc.com bbc.jpg

This will fetch the www.bbc.com index page and save it as a jpg image. Below are a few websites rendered using the wkhtmltoimage tool.

Customizing the output

wkhtmltoimage comes with a plethora of options, a few are shown below, more options can be found in the documentation.

The default output quality of the program is set to ’94′ which can make the size of some images a lot bigger, but you can change it to your liking using the below option.

wkhtmltoimage --quality 50 http://www.bbc.com bbc.jpg

Also by default all the images on a page are rendered in the final image, but you can disable images in the final screen-shot using the following:

wkhtmltoimage --no-images http://www.bbc.com bbc.jpg

You can also set the output height and width of the image (in pixels) as below.

wkhtmltoimage --height 600 --width 1800 http://www.bbc.com bbc.jpg

or crop the image to a specified size;

wkhtmltoimage --crop-h 300 --crop-w 300 --crop-x 0 --crop-y 0 
       www.bbc.com bbc.jpg

Sometimes the JavaScript on the webpage you are rendering can cause problems during rendering, preventing the program from saving the screenshot or causing a huge delay. In such cases you can ask wkhtmltoimage to not run JavaScript on the page while rendering.

wkhtmltoimage --disable-javascript http://www.bbc.com bbc.jpg

Using with PHP

Although this is not a pure PHP solution for taking screen shots, you can wrap the final command in a shell_exec function or download the ‘snappy’ PHP5 wrapper from below. The original library is located here, but as the source keeps changing the examples given here do not work, so use the library given below.

shell_exec('./wkhtmltoimage --quality 50 http://www.bbc.com bbc.jpg');

Below is a short code using ‘snappy’ to take a screen-shot of bbc.com.

<?php
 
/* Tested on Ubuntu 10.0.4, requires PHP 5.3  */
 
namespace Knplabs\Snappy;
 
require_once('Knplabs/Snappy/Media.php');
require_once('Knplabs/Snappy/Image.php');
 
/* 'wkhtmltoimage' executable  is located in the current directory */
$snap = new Image('./wkhtmltoimage');
 
/* Displays the bbc.com website index page screen-shot in the browser */
header("Content-Type: image/jpeg");
$snap->output('http://www.bbc.com');
 
?>

and with a few options added…

<?php
 
/* Tested on Ubuntu 10.0.4, requires PHP 5.3  */
 
namespace Knplabs\Snappy;
 
require_once('Knplabs/Snappy/Media.php');
require_once('Knplabs/Snappy/Image.php');
 
$options = array('zoom' => 0.5, 'no-images' => true);
 
/* 'wkhtmltoimage' executable  is located in the current directory */
$snap = new Image('./wkhtmltoimage-i386',$options);
 
/* Displays the bbc.com website index page screen-shot in the browser */
header("Content-Type: image/jpeg");
$snap->output('http://www.bbc.com');
 
?>

In my opinion you should play with the shell program first till you get to know the complete options and only than use the ‘snappy’ PHP wrapper.

In closing here is the snapshot of my site ,rendered at 50% quality (click to zoom).

Happy rendering!!

<?php
 
require_once "ismobile.class.php";
 
$ismobile = new IsMobile();
 
if($ismobile->CheckMobile()) {
    echo 'Your mobile device is a ' . $ismobile->GetMobileDevice();
}
else {
    echo "It isn't a mobile device!";
}
 
?>

View the following link on your mobile device.

Besides the above functions it can also detect if WAP is being used on the mobile.

$iswap = $ismobile->checkMobileWap();

EasyBasket takes a different approach at creating a shopping cart; although technically complex in its execution, it is extremely simple for the user to install. With EasyBasket you can quickly insert a shopping cart anywhere on your web page with a single line of code. No need of installing a database or a dozen class files. Google Checkout and PayPal Checkout are integrated into the code, all you need to do is change the credentials and your cart is ready to go.

How EasyBasket works

EasyBasket bascially works by manipulating XSL forms. When a item is added on the client page, EasyBasket with the help of jQuery serializes the form and sends it to the server. On the server PHP uses the core.xsl file to update and transform the received form and send it back to the client. The complete shopping cart functions – create/update/add/delete (CRUD) is handled by the XLST logic; this is something original I’ve seen related to shopping carts.

Note that in all this flow a database is never used. This allows small websites having a few items to quickly add a shopping cart to their site.

Other options

EasyBasket supports various skins and also includes drag-drop functionality for adding items.

The basic principle behind the library

Every data filtering/validation library hinges on three basic principles.

The first principle is of preventing users from accessing user input via the PHP superglobals, because the “default” action is to retrieve the raw, potentially dangerous data.

The second principle is preventing ad-hoc filtering/validation code at various places in the application which can be error-prone and difficult to modify.

The final principle is that of simplicity. A validation library should make a programmer’s job easier. Complex solutions should be avoided unless they are the only solution, as programmers tend to bypass intricate solutions citing various reasons for the same.

Installing Inspekt

Inspekt is easy to install. Just download the library and include the ‘Inspekt.php’ in your application with the correct path.

require_once('Inspekt.php');

Caging data

Take the following simple code using Inspekt. Here all the POST data is only made available through the ‘post_cage’ object, once it is initialized. The original POST data is immediately deleted preventing you from accidentally using data from the $_POST array. In short all the POST data is now safety ‘caged’ in the ‘post_cage’ object, which can only be accessed by using the various objects functions.

<?php
 
require_once('Inspekt.php');
 
if(isset($_POST['submit'])) 
{
    /* This will print the $_POST data */
    print_r($_POST);
 
    /* Store all the POST data in a 'cage', 
     * this will also automatically delete 
     * all the original POST data.
    */
    $post_cage = Inspekt::makePostCage();
 
    /* This will now return an empty array */
    print_r($_POST);
}
 
?>
 
<html>
<body>
<form id="myform" name="myform" method="POST">
<input type="hidden" name="fname" value="testString" />
<input type="hidden" name="id" value="500" />
<input type="submit" name="submit" value="submit" />
</form>
</body>
</html>

Example 1.

Accessing ‘caged’ data

Now that we have seen how the POST data is safely stored in a ‘cage’, we will look at how to access and validate the data.

In the above example we have a ‘fname’ html field which we can access from the cage as following, which will print the string “testString”.

.
echo $post_cage->getRaw('fname');
.
.

But wait, what does this buy us, we are just using another object to access the same POST data in a different way. Well this is just one method, which just returns the raw data, the real value comes when we use validation and filtering methods.

Suppose we wanted to make sure that only alpha-numeric characters are allowed in the “fname” variable, we can use the following code which will return the value of the variable if the value is alpha-numeric or ‘false’ otherwise.

.
if($fname = $post_cage->testAlnum('fname')) {
   // Do something here if 'fname' is alphanumeric
}
.
.

Again let us say we have to check if the value of the ‘id’ field lies between 100 – 600, we can use the following:

.
if($post_cage->testBetween('id',100, 600))
{
     // value lies between 100 - 600, do something
}
.
.

Beside the above two, the following are some other useful methods:

* testAlnum (mixed $key)
* testAlpha (mixed $key)
* testBetween (mixed $key, mixed $min, mixed $max, [boolean $inc = TRUE])
* testCcnum (mixed $key, [mixed $type = NULL])
* testDate (mixed $key)
* testDigits (mixed $key)
* testEmail (mixed $key)
* testFloat (mixed $key)
* testGreaterThan (mixed $key, [mixed $min = NULL])
* testHex (mixed $key)
* testHostname (mixed $key, [integer $allow = ISPK_HOST_ALLOW_ALL])
* testInt (mixed $key)
* testIp (mixed $key)
* testLessThan (mixed $key, [mixed $max = NULL])
* testOneOf (mixed $key, [ $allowed = NULL])
* testPhone (mixed $key, [ $country = 'US'])
* testRegex (mixed $key, [mixed $pattern = NULL])
* testUri (unknown_type $key)
* testZip (mixed $key)

Caging other input data

In the above examples we have seen how to add the POST data to a ‘cage’ using the ‘Inspekt::makePostCage’ method. Likewise, we can also use other methods for other input types:

• Inspekt::makeGetCage()
Returns an Inspekt_Cage for the $_GET array

• Inspekt::makePostCage()
Returns an Inspekt_Cage for the $_POST array

• Inspekt::makeCookieCage()
Returns an Inspekt_Cage for the $_COOKIE array

• Inspekt::makeServerCage()
Returns an Inspekt_Cage for the $_SERVER array

• Inspekt::makeFilesCage()
Returns an Inspekt_Cage for the $_FILES array

• Inspekt::makeEnvCage()
Returns an Inspekt_Cage for the $_ENV array

So to ‘cage’ the $_GET data we can use the following:

$get_cage = Inspekt::makeGetCage();

Using the Super Cage

Using a different cage for each different input type can be cumbersome, for this we can use the ‘SuperCage’ method, which encapsulates all the above input data in a single object.

$super_cage = Inspekt::makeSuperCage();

Example 1. can be now be coded as below:

<?php
 
require_once('Inspekt.php');
 
if(isset($_POST['submit'])) 
{
    $super_cage = Inspekt::makeSuperCage();
 
    echo $super_cage->post->testAlnum ('fname') . " ";
    echo $super_cage->post->testBetween('id',220, 600);
}
 
?>
 
<html>
<body>
<form id="myform" name="myform" method="POST">
<input type="hidden" name="fname" value="testString" />
<input type="hidden" name="id" value="500" />
<input type="submit" name="submit" value="submit" />
</form>
</body>
</html>

In conclusion

I find Inspekt a quite interesting validation/filtering library. Although the development seems to have stalled at Version 0.4.1, the code is complete and simple to use. This post has only covered a small portion of the library, for more information you can visit the original source.

phpthumb uses the ‘gd’ library to process the images, so you will need to have gd installed on your system. You can use phpinfo() or the following to quickly check for the same:

<?php
var_dump(gd_info());
?>

If ‘gd’ library is not installed the above will return a ‘Call to undefined function gd_info()’ error.

Simple examples

The following simple code shows how to quickly resize a image.

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
/* Resize to 100x100 pixels */
$thumb->resize(100, 100);
$thumb->show();

..rotate a image.

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
/* Rotate the image  by 180 degrees */
$thumb->rotateImageNDegrees(180);
 
$thumb->show();

..crop a image.

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
/* $startX, $startY, $cropWidth, $cropHeight */
$thumb->crop(50, 50, 100, 100);
 
$thumb->show();

..resize by a percentage.

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
/* Percentage can be less than or greater than 100 */
$thumb->resizePercent(60);
 
$thumb->show();

…or save it to a different format. Formats can be any from the following:
‘GIF’, ‘JPG’, ‘PNG’.

require_once '../ThumbLib.inc.php';
 
$image_path = 'images/';
 
$thumb = PhpThumbFactory::create($image_path  . 'test.jpg');
$thumb->resize(300, 300);
 
$thumb->save($image_path  . 'test.png', 'png');

Thumbnail options

While creating a thumbnail you can pass various options in an array; for example, to scale an image up to the desired dimensions and to set the jpeg quality to 60 we will use the following code.

require_once '../ThumbLib.inc.php';
 
$options = array('resizeUp' => true, 'jpegQuality' => 60);
 
$thumb = PhpThumbFactory::create('images/test.jpg', $options);
$thumb->resize(300, 300);
$thumb->show();

More options can be found here and documentation regarding other functions can be found here.

Custom plugins

phpthumb also lets you create custom plugin for further image processing. A sample plugin for reflection is provided in the download code, a example of which is shown below:

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
/* Params: $percent, $reflection, $white, $border, $borderColor */
$thumb->createReflection(40, 40, 10, true, '#a4a4a4');
$thumb->show();

Chaining functions

To quickly apply various formatting to the image we can chain various functions as shown below. The following code will crop an image, resize it to 150% of the original size and then add a reflection to the final image.

require_once '../ThumbLib.inc.php';
 
$thumb = PhpThumbFactory::create('images/test.jpg');
$thumb->crop(93,58, 40, 40)
      ->resizePercent(150)
      ->createReflection(40, 40, 80, true, '#a4a4a4');
 
$thumb->show();

The output of the above is shown below.
