        $port = $prt;

       $fp = @fsockopen($site, $port, $errno, $errstr);
            if (!$fp)
              // return $port;
                return "ERROR: $errno - $errstr<br />\n";

    2:{'key':12,'name':'Canal 2','ip':'xx.xx.xx.xxx','tcp_port':13461,'udp_port':13461,'state':STATE_NONE,},
    3:{'key':13,'name':'Canal 3','ip':'xx.xx.xx.xxx','tcp_port':13491,'udp_port':13491,'state':STATE_NONE,},
    4:{'key':14,'name':'Canal 4','ip':'xx.xx.xx.xxx','tcp_port':13521,'udp_port':13521,'state':STATE_NONE,},

Solution

  • Logical to me: the fsockopen() first argument $site is not set. I presume it should be $ip instead of $site. By the way you should be careful as fsockopen() returns a ressource, when checking for it's return you should strict test.

    public function check_ch($prt)
{
    $ip = "xx.xx.xx.xxx";

    $fp = @fsockopen($ip, $prt, $errno, $errstr);
    if ($fp === false) {
        // return $port;
        return "ERROR: $errno - $errstr<br />\n";
    } else {
        return 1;
    }
}

    EDIT: When you silence a function with a @, if you get a problem, the first reflex to have is to unsilence it. You should have a report that $site is not set if it was unsilenced ;)
