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.
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.

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”;
can any one help me out how to print down the value of the array..?
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
this is great stuff, thank you. i had to mess with this a little more than I wanted but finally got it.
