check exec, or you could request the file (assuming its a web server) using file() fopen() etc....

$strPing= ping -ns www.whatever.com 4 4;
echo "<pre>";
echo $strPing;
echo "</pre>";

use `, not '

Here's another way to PING a host using PHP. It's more clumsy but more compatible.

<?

$host='CHANGETHISTOYOURHOST';
$strPing= ping $host;
$posstring = strpos($strPing, "Please", 1);
if ($posstring == 0)
{ echo "Server online!"; }
else
{ echo "Server offline!"; }

?>

This will return "Server online!" if the server is online and "Server offline!" if the server is offline
