通过php中的特定端口（fsockopen）ping服务器

Question

function checkServer($domain, $port=80) { global $checkTimeout, $testServer;

$status = 0;

$starttime = microtime(true);
$file = @fsockopen ($domain, $port, $errno, $errstr, $checkTimeout);
$stoptime = microtime(true);

if($file)
{
    fclose($file);
    $status = ($stoptime - $starttime) * 1000;
    $status = floor($status);
}
else
{
    $testfile = @fsockopen ($testServer, 80, $errno, $errstr, $checkTimeout);
    if($testfile)
    {
        fclose($testfile);
        $status = -1;
    }
    else
    {
        $status = -2;
    }
}

return $status;

}

the testserver is google.sk, and checkTimeout is 10 seconds. This actually works, but when i try to run it in a loop for about 50 times, and do other stuff (mysql queries and things like that), it's not slow, but it causes 100% load of my CPU until the script ends. It's a single apache proccess that drives my cpu crazy ... So i wanted to ask you if you have any ideas about it. maybe some tip how to do the same in python or bash or so will be appreciated.

Thank you for the responses :)
