PING using php

I have been playing around with CURL and its awesomeness for a potential idea and had to use some data retrieved by sending a ICMP packet to the host. This was required to check to check stuff like host availability, packet loss etc. The standard stuff. Doing this would be fairly straightforward if you wanted to use the exec function. However getting the data back as a data structure can be a pain.
Pear has an interesting packge Net/Ping does does all that very neatly for you. Here is the code snippet for that.

<?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 = $ping->ping('rajatpandit.com');
      print_r($rawData);
    }

?>

and the data that you get back, is a pretty useful structured array.

Net_Ping_Result Object

    [_icmp_sequence] => Array
        (
            [1] => 310
            [2] => 300
            [3] => 318
            [4] => 301
        )

    [_target_ip] => 67.205.0.93
    [_bytes_per_request] => 32
    [_bytes_total] => 128
    [_ttl] => 238
    [_raw_data] => Array

            [11] =>     Minimum = 300ms, Maximum = 318ms, Average = 307ms
        )

    [_sysname] => windows
    [_round_trip] => Array
        (
            [min] => 300

        )

Sweet!
