会话数据在本地工作但不在远程服务器上工作

this is my code. plain and simple.

1) first.html

<body>
    <?php
    session_start();
    ...
    $somearray = $Object->method($somevar);
    $_SESSION["somearray"] = $somearray;
    ...
    ?>
</body>

1) second.html

<body>
    <div id="map_canvas">
        <script language="javascript" type="text/javascript">
        <?php session_start(); ?>
        some_render_function(<?php echo json_encode($_SESSION["somearray"]); ?>);
        </script> 
    </div>       
</body>

perfectly working code on localhost.

There are 2 facts that can help you guys to come up with where's the problem here.

1)If you check the source of the page second.html offline and online you can respectively see some_render_function('all the stuff from the json') and some_render_function(NULL)

2)If i check my shared server folder i can see a directory called php_session with apparently all the correct files in it (of all the sessions opened when i tested my project, with CORRECT data in it)

Any hints?

    Hello session_start ( http://php.net/manual/en/function.session-start.php ) should always be the first parameter on your page ...

    Example

    First Page 

    <?php session_start();?>
<html>
<head>
<title>First</title>
</head>
<body>
    <?php
    $somearray = $Object->method($somevar);
    $_SESSION["somearray"] = $somearray;
    ?>
</body>

</html>

    Second Page

    <?php session_start(); ?>
<html>
<head>
<title>Second</title>
</head>
<body>
    <?php
    var_dump($_SESSION["somearray"]);
    ?>
</body>
</html>
