can I rely on $PHP_SELF ???

I'm trying to create the most portable authentication script possible... so I'll have in all my files something like: session_start(); require("../include.conf.php"); require(INCLUDE_DIR."/autentica.inc.php"); AutenticaAdmin( $PHP_SELF ); where AutenticaAdmin() will authenticate the admin and if successfull redirect to $PHP_SELF (the file trying to be accessed)... the question is: is $PHP_SELF reliable for this? Cuz I remember my first Apache configuration ever (I mean the first... total disaster)... and $PHP_SELF returned something very weird like '/php/php.exe/dir/file.php'... so my question is... will $PHP_SELF allways work or some servers will give me eerie info??? _____________________________ .
