Ping a server using PHP

Posted in: php | Save to del.icio.us | Twit This! 13 Sep 2008

PEAR’s Net_Ping is a niffty wrapper class for executing ping calls from PHP. You can use it to check if a remote server is responding correctly. The library can be download from here.

Installation

Net_Ping being a Pear package we will use the Pear installer to download and install it. I recommend to always use the Pear installer to download packages rather than downloading it manually as the Pear installer automatically downloads any dependent packages.

pear install Net_Ping-2.4.4

Usage

A example of using Net_Ping is given below.

<?php
 
    require_once "Net/Ping.php";
 
    $ping = Net_Ping::factory();
 
    if(PEAR::isError($ping))
      echo $ping->getMessage();
    else
    {
      /* Number of packets to send */
      $ping->setArgs(array('count' => 4));
      $rawData = $ping->ping('google.com');
      print_r($rawData);
    }
 
?>

The output of the same is shown below.

Net_Ping_Result Object
(
    [_icmp_sequence] => Array
        (
            [1] => 310
            [2] => 300
            [3] => 318
            [4] => 301
        )
 
    [_target_ip] => 64.233.167.99
    [_bytes_per_request] => 32
    [_bytes_total] => 128
    [_ttl] => 238
    [_raw_data] => Array
        (
            [0] => 
            [1] => Pinging google.com [64.233.167.99] with 32 bytes of data:

        )
 
    [_sysname] => windows

        (
            [min] => 300

Hello,

I have found your post about pinging in php with the pear net_ping class.

Could you please tell me how I can use the output data? I have no clue how to use the data so I echo for example the IP adres on a page.

By thanking you in advance,

To get the IP element for example use the following:

$ip = $rawData->_target_ip;

and so on.

Now if you want tot get the ‘_raw_data’ element, you will see that it is an array, so we will have to loop through the same, like this:

foreach($rawData->_raw_data as $data)
echo $data . “\n”;

A easy way is to run the code from the command line and redirect the output to a text file, which you can print as shown below. Assuming your code filename is Ping.php.

c:\php Ping.php > pingdata.txt
