get_included_files — Returns an array with the names of included or required files
Gets the names of all files that have been included using include, include_once, require or require_once.
This function has no parameters.
Returns an array of the names of all files.
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.
Example #1 get_included_files() example
<?php
// This file is 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";
}
?>The above example will output:
/path/to/abc.php /path/to/test1.php /path/to/test2.php /path/to/test3.php /path/to/test4.php
If you have a MAIN php script which you don't want to be included by other scripts, you could use this function. For example:
main.php:
<?php
function blockit()
{
$buf = get_included_files();
return $buf[0] != __FILE__;
}
blockit() and exit("You can not include a MAIN file as a part of your script.");
print "OK";
?>
So other script couldn't include main.php to modify its internal global vars.It's perhaps not clear from the existing docs that the returned list contains nested include files as well.
That is, if A.php includes B.php, and B.php includes C.php, the result returned when calling get_included_files() from inside A.php WILL contain 'C.php'.As is often the case, YMMV. I tried the __FILE__ and SCRIPT_FILENAME comparison and found this:
SCRIPT_FILENAME: /var/www/cgi-bin/php441
__FILE__: /raid/home/natpresch/natpresch/RAY_included.php
As an alternative:
count(get_included_files());
Gives one when the script is standalone and always more than one when the script is included.This is a great way to emulate Python's '__name__ = "__main__"'
<?php
if(get_included_files()[0] === __FILE__) doStuff();
?>
