Way to get absolute path of file PHP

Question

Is there a way to get the absolute path of a file while having it included in another script?

So I'm trying to include a file that's in folder A while I'm in folder B but it keeps trying to refer to folder B's location.

I've tried dirname, $SERVER['PHP_SELF'], cwd(), but they still return a relative path.

@SuperCoolHandsomeGelBoy No, that only gives me up to /var/www/html. My file is nested within a couple more folders in. — A. L

You can try like this

include dirname(__FILE__).'/../yourfile.php';

Since PHP 5.3.0 you can use also the magic constant __DIR__ More info in the docs

Another way is

$rootDir = realpath($_SERVER["DOCUMENT_ROOT"]);

include "$rootDir/yourfile.php";

+1 for the options! that made me think of this (common?) line: $base_dr = basename(__DIR__); (where the directory at the top of the structure drives biz logic somehow).

for some strange reason $rootDir = realpath($_SERVER["DOCUMENT_ROOT"] .'/../yourfile.php' ); will not work

__FILE__

That is the absolute path to the file being executed.

simple usage examples:

echo __FILE__;

echo "This file is: " . __FILE__;

If you need the real path you can use the SplFileInfo.

$path = new SplFileInfo(__FILE__);
echo 'The real path is '.$path->getRealPath();
