If the directory sizes are small I can manually delete those unwanted files. But if the directory sizes are big or if they are nested deeply, than it can be quite time consuming. Maybe you left a couple of huge MySQL dumps somewhere and forgot to delete them, thus increasing the project file size. And if you are trying to do the cleanup on a online server then it can be even more painful.

Or maybe you are just curious to find how various types of files are taking up your directory space.

Whatever the reason, below is a small php script that displays the distribution of files in a particular directory and its sub-directories by its type. This can be handy if you would like to see which files are taking up space in your project. Although you can easily do such kind of things with a variety of desktop tools, the following code can easily be used online, or integrated into your existing php application.

Displaying file stats

The class allows you to display the stats in a text format on the command-line or in a HTML format, which you can use online.

To display a text based stats you can use the class as given below and run it from the command line.

<?php
 
include('FileTypeStats.php');
 
$stats = new File_Type_Stats;
$stats->getText("/localhost/home/project");
 
?>

Below is the output for the above. Note that files that do not have an extension are not displayed.

D:\localhost\test\scan_dir>php textStat.php
 
=====================================================
File Type      Total Files      Total Size     %

 prefs                1              0 kb    (0.00 %)
 txt                  2              0 kb    (0.00 %)

Setting a path in the function can be a bit limiting, so you can take the path argument from the command line instead.

<?php
 
include('FileTypeStats.php');
 
$stats = new File_Type_Stats;
$stat_data = $stats->getText($argv[1]);
?>

Now you can get the path from the command line.

D:\localhost\test\scan_dir>php textStat.php /localhost/home/project/

Set the textStat.php in you path variable, and you will have the file stat functionality available anywhere.

Someone could have written this class as a shell script easily, but the advantage of doing it in PHP is that we can also have a HTML version of the above stat display, as shown below.

To display HTML table based stats you can use the class with the getHtml() method and run it from the browser.

<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<?php
 
include('FileTypeStats.php');
 
$stats = new File_Type_Stats;
$stat_data = $stats->getHtml("/localhost/home/project");
echo $stat_data;
 
?>
</body>
</html>

Below is the HTML output.

The style is defined in a CSS, so you can customize it to your liking.

A word of caution. For hugely nested directory running into thousands of files the script can timeout, so make sure that you increase the php max_execution_time in your script to an appropriate number.

set_time_limit(600);

Most programmers will implement it using Perl a shell script or through a editor. Perl offers itself as an excellent tool for the required purpose; we PHP programmers are not quite so lucky in that matter. Search/replace is easier from a shell prompt or an editor, but what if you have to do the same programatically in php. File_SearchReplace is a pear package that helps you search/replace in files through a nice object oriented interface.

Installation
Pear installation as usual is simple.

c:/> pear install File_SearchReplace

Doing a simple search & replace
The following is an simple example code that searches the file ‘fruits.txt’ and replaces all occurrences of ‘apples’ with ‘oranges’. The getNumOccurences function returns the total number of replaced strings in the file.

<?php
 
include 'File/SearchReplace.php' ;
 
$files_to_search = array("fruits.txt") ;
$search_string  = "apples";
$replace_string = "oranges";
 
$snr = new File_SearchReplace($search_string,
                              $replace_string,
                              $files_to_search,
                              '', // directorie(s) to search
                              false) ;
 
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
?>

The fourth option in the File_SearchReplace specifies a optional directory name to search. If the directory name is empty than the files will be searched in the current directory or in the respective path if a path is also included with the filename. Following is an example if you want to search all files in the directory ‘nature/fruits’.

<?php
 
include 'File/SearchReplace.php' ;
 
$files_to_search = array();
$direc_to_search = array('nature/fruits/');
 
$search_string  = "apples";
$replace_string = "oranges";
 
$snr = new File_SearchReplace($search_string,
                              $replace_string,
                              $files_to_search,
                              $direc_to_search, // directory to search
                              true) ; // 'true' to search subdirectories
 
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
?>

All the four starting options of File_SearchReplace are of mixed type; i.e they take a string or an array of strings as their options. For example in the following all occurrences of ‘apples’ will be replaced by ‘oranges’ and that of ‘pears’ by ‘grapes’.

<?php
 
include 'File/SearchReplace.php' ;
 
$files_to_search = array();
$direc_to_search = array('nature/fruits/');
 
$search_string  = array('apples', 'pears');
$replace_string = array('oranges', 'grapes');
 
$snr = new File_SearchReplace($search_string,
                              $replace_string,
                              $files_to_search,
                              $direc_to_search,
                              true) ;
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
?>

You don’t have to create a new instance everytime you need a new search, you can set the various parameters through the interface provided by the File_SearchReplace class as shown below.

<?php
 
include 'File/SearchReplace.php' ;
 
$files_to_search = array();
$direc_to_search = array('nature/fruits/');
 
$search_string  = array('apples', 'pears');
$replace_string = array('oranges', 'grapes');
 
$snr = new File_SearchReplace($search_string,
                              $replace_string,
                              $files_to_search,
                              $direc_to_search,
                              true) ;
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
/* Start a new search */
 
$snr->setFind( "oranges") ;
$snr->setReplace( "berries") ;
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
?>

Regular Expression search
You can also use a regular expression in a search string, but before that we must specify what kind of search is required with the ‘setSearchFunction’ as shown below. The following example replaces all occurrences of ‘color’ or ‘colour’ with the capital ‘COLOR’.

<?php
 
include 'File/SearchReplace.php' ;
 
$files_to_search = array();
$direc_to_search = array('test/graphics/');
 
$search_string  = '/col(o|ou)r/';
$replace_string = 'COLOR';
 
$snr = new File_SearchReplace($search_string,
                              $replace_string,
                              $files_to_search,
                              $direc_to_search,
                              true) ;
 
$snr->setSearchFunction("preg");
$snr->doSearch();
 
echo "The number of replaces done : " . $snr->getNumOccurences();
 
?>

The setSearchFunction takes one of the following four options:

normal – default
quick – use str_replace()
preg – use preg_replace()
ereg – use ereg_replace()

More information on this options can be found here.

In conclusion
The package can be quite useful when you want to replace large quantities of text programatically. As it works on plain strings and regular expressions, its can be quite a handy tool in many occasions.
