Socket_Connect returning unusual error

[Adam Hubscher <webmaster@xxxxxxxxxxxxxxxx>]

Warning: socket_connect() expects parameter 3 to be long, string given 
in testing.php on line 21
Couldn't Create Socket: Success

It actually spits that across for every socket I'm trying to connect.

I'm doing an online status for multiple servers, which I have tested to 
work when I simply do a socket_connect($sock,$url,$port); on the port 
numbers of the various servers. The servers all reside on the same IP 
address.

The script actually works manually, ie if i put the actual port in to 
the socket_connect function call. However, as soon as I put the variable 
in - it wont work.

The code looks like so:

foreach ($servers as $key => $value){

    $currport = $servers[$key]['Port']; // was attempting this to see 
if it would work - it did not either. Normally tried 
$servers[$key]['Port'] directly.
    if(!socket_connect($sock, $ip, $currport)){
        print("Couldn't Create Socket: " . 
socket_strerror(socket_last_error()). "\n"); // Debugging purposes
        $output .= "Server Name: " . $Servers[$key]['Name']. " ~~ 
Offline <br />";
    }
    else{
        $output .= "Server Name: " . $Servers[$key]['Name']. " ~~ 
Online <br />";
    }
}

I cant quite find anything that is... actually wrong with the code. I 
dont understand the error all that much either, as it says "Success" in 
it. Needless to say - I'm thoroughly confused!

Anyone help me out?

Thanks!
