A way to get the absolute path to a PHP file

Question

Is there a way to get the absolute path to a file when it is included in another script?

So, I'm trying to include a file that is in folder A when I am in folder B, but it continues to try to link to the location of folder B.

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

Answer 1

You can try like this

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

With PHP 5.3.0, you can also use the magic constant __DIR__ more information in the docs

Another way -

 $rootDir = realpath($_SERVER["DOCUMENT_ROOT"]); include "$rootDir/yourfile.php"; 

Answer 2

You want __FILE__ , which is an absolute file path.
