Ping a Server

BulldogGC

Hey guys,

I've spent hours browing through tutorials, reading these forums, etc. and cannot find an answer that works. I've gotten countless ping results, unformatted, used countless script to no avail, etc.

All I'm looking for is a simple way to friggin ping a website.
And display how fast it's average ms return was .... that's all 🙁

Someone plllllllease help

this just tests if it's live but can easily be modified:

function isURL($Value) {
    $parsed = parse_url($Value);
    if($parsed['scheme'] != 'http' || $parsed['host'] == '') {
        $parsed['scheme'] = 'http';
        $parsed['host'] = BASEURL;
    } //end if
    elseif(!checkdnsrr($parsed['host'],'A')) {return 0;}

$fp = fsockopen ($parsed['host'], 80);
fputs($fp,"GET $Value HTTP/1.0\n\n");
$line = fgets($fp, 1024);
if (stristr($line, '200 OK')) {$end = 1;}
else{$end = 0;}
fclose($fp);
return $end;
} //end isURL

you can't do a true ping in php because it relies on a type of packet not available from inside of php.

What I ended up coming up with is as follows:

function ping($link) { 
        $link = preg_replace('![url]http://www.[/url]!','',$link); 
		$link = preg_replace('/:.*/','',$link);
		$cmd = `ping -c1 -w1 $link`;
        if (preg_match('!time=(.+) ms!', $cmd, $m)) { 
                print "<font color='lime'><strong>ALIVE</strong></font> (".$m[1] . "ms)"; 
        } else { 
                print "<font color='red'><strong>DEAD</strong>"; 
        } 
}

This shows only the ping in terms of #ms ...

I'm sure some of you will find it helpful.

Not quite. By using the socket functions with sock_raw and icmp you can do icmp pings. It's just a matter of constructing the packet correctly and reading the response.
