mta_sdk, PHP, Could not connect to...

[XFawkes]

NVM the code works, the problem is that my mta server hoster allows only 22027 HTTP port which is closed / blocked by firewall on the web server. Any possibilites how to send the data from 1 to 2 servers?

Hello, I am trying to create a server monitor on my website.

The lua code looks like this:

resource: WebSend

function sendInfoHTTP() 
    Players= {} 
    for i,thePlayer in ipairs(getElementsByType("player")) do 
        Players[i] = {} 
        Players[i][1] = (getPlayerName(thePlayer) and getPlayerName(thePlayer) or "?") 
        Players[i][2] = (getElementData(thePlayer,"name") and getElementData(thePlayer,"name") or "?") 
        Players[i][3] = (getElementData(thePlayer,"surname") and getElementData(thePlayer,"surname") or "?") 
        Players[i][4] = (getElementData(thePlayer,"id") and getElementData(thePlayer,"id") or "?") 
        Players[i][5] = (getElementData(thePlayer,"pts") and getElementData(thePlayer,"pts") or "?") 
        Players[i][6] = (getPlayerPing(thePlayer) and getPlayerPing(thePlayer) or "?") 
    end 
     
    return getPlayerCount(), getMaxPlayers (), Players 
end 
  

It works, the function is exported and when I am trying to connect from my browser:

IP:Port/WebSend/call/sendInfoHTTP I get the correct results.

[ 1, 60, [ [ "player1", "somename", "surname", 221, 4, 31 ] ,[ "player2", "somename2", "surname2", 11, 32, 64 ] ] ]

The problem is that when I am trying to do it on my webside I can't connect to the game server [which stands on a different hoster].

My PHP code:

  
<?php 
include( "mta_sdk.php" ); 
  
$host = 'xx.xx.xx.xx'; 
$port = 'xxxxx'; 
$user = 'user'; 
$pass = 'password'; 
  
$mtaServer = new mta($host, $port, $user, $pass); 
$resource = $mtaServer->getResource ( "WebSend" ); 
$retn = $resource->call ( "sendInfoHTTP" ); 
$pCount = $retn[0]; 
$pMax = $retn[1]; 
$pData = $retn[2]; 
?> 
  
.... html code with the output, css styles, tables etc  
  

I get an error message:

Fatal error: Uncaught exception 'Exception' with message 'Could not connect to xxxxxxxxxx' in xxxxxxx/mta_sdk.php:146 Stack trace: #0

Does your server have a static ip?

If it doesn't then ever time you restart your hosting computer, then you would need to change the "host" variable.

Eh, I need to ask something, how are you getting the results on your browser without using the php echo function? I'm trying to do the same thing, get a return from a .lua file with http as true in the meta export, but nothing seems to be returned to the .php page.

NVM the code works, the problem is that my mta server hoster allows only 22027 HTTP port which is closed / blocked by firewall on the web server. Any possibilites how to send the data from 1 to 2 servers?
