I'm working on a webpage which uses PHP to get the state of some servers located in the same machine (exactly 7 servers).
When I was only getting the state of 1 server the page did load fast and everything was ok, but after adding all the servers it takes like 5 seconds to load and sometimes it times out and doesn't load at all.
To get the server status I am using this .php which uses sockets:
<html>
<?php
class Status {
public $server;
public $online, $motd, $online_players, $max_players;
public $error = "OK";
function __construct($url, $port = '25565') {
$this->server = array(
"url" => $url,
"port" => $port
);
if ( $sock = @stream_socket_client('tcp://'.$url.':'.$port, $errno, $errstr, 1) ) {
$this->online = true;
fwrite($sock, "\xfe");
$h = fread($sock, 2048);
$h = str_replace("\x00", '', $h);
$h = substr($h, 2);
$data = explode("\xa7", $h);
unset($h);
fclose($sock);
if (sizeof($data) == 3) {
$this->motd = $data[0];
$this->online_players = (int) $data[1];
$this->max_players = (int) $data[2];
}
else {
$this->error = "Cannot retrieve server info.";
}
}
else {
$this->online = false;
$this->error = "Cannot connect to server.";
}
}
}
?>
</html>
And on the page where the state of the servers display the php code is like this:
= newonline_players;
echo "/";
echo $server->max_players;
echo ")";
$var = $server->online;
if ($var == true) {
echo "<a href='#' class='online'>ONLINE</a>";
}
else {
echo "<a href='#' class='offline'>OFFLINE</a>";
}
?>
The status of the server is retrieved okay and everything works, but what I wanted to know if anyone has any idea to avoid the webpage timing out or improve the load time in any way?
Thanks.
