Here's a function that finds the Server Software of a server and returns it. The timeout is at
1 second, but I would prefer, if you use this function many times on a page, to set it lower.
<?php
function get_server_software($domain) {
$fp = fsockopen($domain, 80, $errno, $errstr, 1);
if (!$fp) {
return("");
}
else {
fputs($fp, "HEAD / HTTP/1.1\r\nHost: " . $domain . "\r\n\r\n");
while (!feof($fp)) {
if (preg_match("/\bServer:/", $server = fgets($fp, 256))) {
fclose($fp);
return(substr($server, 8, -2));
}
}
fclose($fp);
}
}
?>
