jQuery .load和PHP会话启动

Question

I am currently working on a game in PHP and jQuery and at some point I will need to use the .load() from jQuery to load a PHP page into a div. That page will load some player information based on their login information, account id, etcetera, stored into an array inside $_SESSION["arrayname"].

It works perfectly on all sites, except those where jQuery load() is use. On easyphp, I got no errors, but on my web host server im getting this:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /fr/game/map.php:1) in fr/game/map.php on line 6

Here is my code:

<?php
 require_once("../../connectionRO.inc.php");

//used to check if we see the array in session, and i dont when i load it with jquery
if(!ISSET($_SESSION["comptejeu"])) 
{
    require_once('../../classInfoCompte.php');
    session_start(); 
    require_once('../../lg.php');
    require_once("./glg.php");
}

$ic = new infoCompte;
    $ic = $_SESSION["comptejeu"];   
?>

I understand that at this point a lot of stuff is already output to the page before that is loaded. Could anyone point me to a better way to retrieve the information that I need from that array to build my object from my class?

Thank you.

Since you are getting this error as output started at /fr/game/map.php:1 (note: line 1) I will place money on you having whitespace or a BOM before the opening <?php tag in /fr/game/map.php.

Make sure the opening < is the first character in the file. If you file is UTF-8, make sure it is UTF-8 without BOM, or convert it to ASCII.

Wrong:

<?php

Right:

<?php
