get_required_files()/get_included_files() does not work as docuemented
http://www.php.net/manual/en/function.get-required-files.php

Tested under Apache 1.3.17 w/ mod-ssl, mod-gzip, and other modules comes with apache. RedHat 7.0.1/j. PHP 4.0.4pl1 running as apache module.

I found strange require_once() behaviour (to be reported as bug) and I also found this problem.

If this is not a script engine problem, then it should be documentation problem. Hope this info helps developer/documentation team.

Following code is identical to the example in manual.
<?php

require_once ('local.php');
require_once ('../inc/global.php');

for ($i=1; $i<5; $i++) {
  include_once 'util'.$i.'php';
}

echo '<pre>';
echo "Required_once files\n";
print_r (get_required_files());

echo "Included_once files\n";
print_r (get_included_files());

echo date('H:i:s',time());
echo '</pre>';

?>

I get
