Export score on php website with SDK

[supremedialect]

Hello everyone this is my first post please take it easy on me.
here goes nothing.

 

I followed xxmadexx's tutorial https://forum.multitheftauto.com/topic/74834-introduction-to-the-php-sdk/

It works and my site show the users. but I was wondering how do I go about exporting more information such as score and other information stored on the server.

 

This is my server.lua file

function getAllPlayersForWebsite ( )
    local players = {}
    for k, player in ipairs( getElementsByType ("player") ) do
        local name = getPlayerName( player )
        table.insert( players, name )
    end
    return players
end

my meta xml

<meta>
    <info author="xXMADEXx" type="script" version="1.0" name="MTA PHP" />

    <!-- Include our awesome script -->
    <script src="server.lua" />

    <!-- Export our function -- Make sure to allow HTTP to access it -->
    <export function="doPrint" type="server" http="true" />
<export function="getAllPlayersForWebsite" type="server" http="true" />

</meta>

 

and the php file

<?php

include "sdk/mta_sdk.php";   # Include the MTA PHP SDK - Give us the classes and methods that we'll need

$MY_SERVER = [
    "host" => "54.153.65.51",        #The host/IP of your MTA server
    "http_port" => 22005,         #The HTTP port for your MTA server (Default 22005)
    "http_user" => "user", #The username that we created in the previous step
    "http_pass" => "password"     #The password for the username that we created
];


#Create a new mta object
$SERVER = new mta ( $MY_SERVER['host'], $MY_SERVER['http_port'], $MY_SERVER['http_user'], $MY_SERVER['http_pass'] );



try {

    $RESOURCE = $SERVER->getResource ( "mta_php" ); # We need to get our resource Object

 $RESULT[] = $RESOURCE->call ( "getAllPlayersForWebsite" );

    foreach ( $RESULT [ 0 ] [ 0 ] as $index=>$playerName ) {
      print_r ( $playerName );
echo "<br /><br />";
    }

#Catch any errors that occurred
} catch ( Exception $e ){
    #Output error message
    echo "<strong>Oops, Something went wrong!</strong><br />Error: {$e->getMessage()}<br /><br />e printout:<br />";

    #Print the error table
    print_r ( $e );
}

?>

 

Where should I start?
