[SOLVED] DOCUMENT_ROOT

[jaymc]

I use $_SERVER['DOCUMENT_ROOT'] to check the path of a script however I have just realised if you run a script outside of apache, $_SERVER variable does not contain anything

 

So my question is, when running php script via cronjob or command line how can I retreive the document root of the file?

well...what are you trying to accomplish exactly...you have a couple options:

 

getcwd() - Gets the current working directory

dirname(__FILE__) - Gets the directory the current file is in

 

edit: __FILE__ is a global variable by the way, not a typo

dirname(__FILE__) is what I was looking for

 

Thanks.

Wait sorry it doesn't do what I need

 

<?
// this php file exists in /home/jay/live/www/scripts/file.php
// I want $dir to = /home/jay/live/www/scripts/
// not /home/jay/

include("/home/jay/global.php"); // this has $dir = dirname(__FILE__);

echo $dir;
?>

From php.net. highlighted is the problem

 

__FILE__ : The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2,

There is no good way to determine a DOCUMENT_ROOT in this situation. Your global.php is outside of your site's directory. You could always do this:

$dir = dirname(__FILE__).'/live/www/scripts/';

 

or how about:

$dir = dirname(realpath($_SERVER['SCRIPT_NAME']));

Cheers I've sorted it
