(PHP 4, PHP 5)

get_included_files --  Returns an array with the names of included or required files


array get_included_files ( void )

Returns an array of the names of all files that have been included using include(), include_once(), require() or require_once().

The script originally called is considered an "included file," so it will be listed together with the files referenced by include() and family.

Files that are included or required multiple times only show up once in the returned array.

Note: Files included using the auto_prepend_file configuration directive are not included in the returned array.

Example 1. get_included_files() example (abc.php)


include 'test1.php';
include_once 'test2.php';
require 'test3.php';
require_once 'test4.php';

$included_files = get_included_files();

foreach ($included_files as $filename) {
    echo "$filename\n";


will generate the following output:


Note: In PHP 4.0.1pl2 and previous versions get_included_files() assumed that the required files ended in the extension .php; other extensions would not be returned. The array returned by get_included_files() was an associative array and only listed files included by include() and include_once().

See also include(), include_once(), require(), require_once(), and get_required_files().
