Problem with including php content file in header template

[jafik2005]

Hello,

I tried to include content of php file in my header template using the procedur here http://www.vbulletin.com/docs/html/t..._externalfiles , So i created a php file "test.php" in the root of my website folder which content is :

PHP Code:

 <?php echo 'hello' ?>

then i created a plugin for the global_start :

PHP Code:

  ob_start();
  include('test.php');
  $includedphp = ob_get_contents();
  ob_end_clean(); 


I tried then to insert {vb:raw includedphp} in my header template but nothing appears in my header.

What is for you the problem ?

Thank you in advance for your answer

PS : I tried to change the structur of the path ("/test.php ", "../test.php", Absolute path...) but in vaine
Ps : The use of plugins is activated from the Vbulletin Option
