I load a page within my template system, the page looks like this
<?php
// Header
 $classes = array('table.class.php','sql.class.php');
 $functions = array('mail.inc.php');
 
// Content
 ..
?>

When i load the page, i use ob_get_contents, like this:
ob_start();
require $file;
$inc = ob_get_contents();
ob_end_clean();
return array(
	'header_menu'=>$usemenufile, 
	'header_js'=>$javascripts, 
	'header_css'=>$stylesheets, 
	'header_template'=>$usetemplate, 
	'header_class'=>$classes, 
	'header_function'=>$functions,
	'page_content'=>$inc
);

Now, when i output the page, everything works, but it dont load the classes/function untill the
end. So i cant use them..

i output like this (this is the short version, without checking the file etc..

$lh = $template->load_page("somepage.php");

foreach($lh['header_class'] as $a) {
  require($a);
}

then i print the page
print $template->showpage($lg['page_content']);
