get_included_files — Restituisce una matrice con i nomi dei file inclusi o richiesti
Restituisce una matrice contenente i nomi di tutti i file che sono stati includi tramite le funzioni include, include_once, require oppure require_once.
Lo script originario viene considerato come 'file incluso', pertanto sarà elencato insieme agli altri file referenziati da include e simili.
File che sono inclusi più volte saranno elencati soltanto una volta sola
Nota:
File inclusi tramite la direttiva
auto_prepend_filenon saranno inseriti nella matrice.
Example #1 Esempio di uso di get_included_files() del file (abc.php)
<?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";
}
?>l'esempio visualizzerà:
abc.php test1.php test2.php test3.php test4.php
Nota:
In PHP 4.0.1pl2 e nelle versioni precedenti get_included_files() assumeva che i file inclusi avessero come estensione
.php; file con altre estensioni erano ignorati. La matrice restituita da get_included_files() era una matrice associativa e riportava soltanto i file inclusi con include e include_once.
Vedere anche include, include_once, require, require_once e get_required_files().
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();
?>
