PING Check

[MikeA]

$ip = '192.168.0.1'; 
$ping = ping($ip);  

if(!$ping) echo 'Ping timed out.'; else  

echo 'ping time: ' . $ping . ' ms';  

function ping($ip) {  

echo 'IP: '. $ip . '<hr>';  

$result = `ping -c 1 $ip`;  

$a = strpos($result, "time=");  

$b = strpos($result, " ms");  

if (!$a || !$b) {  

return FALSE;  

}  

$a = $a+5;  

$r = substr($result, $a, $b-$a);  

return $r;  

} 

I got this code from these forums. If you run this little code from the linux shell prompt, it works flawlessly...if you run it from a browser window, it always reports the IP as "timed out". Anyone have any ideas why it's doing this?

You are attempting to run ping as httpd or apache (depends on what apache is running as) and ping requires root access on most systems.
