Getting location bar and stripping file-ending of a string..

Hey! I have a few questions: 1. How could I get the browser's location bar value (the full path of the

    file we are dealing with)?
    I have index.php3 which include's an external php3 script("ext.php3"), and I need
    the 'ext.php3' script to get the full path of the main file it was called from - 'index.php3'.

2. Let's say I have a string such as: "http://www.blabla.com/dir1/dir2/file.php3",

    How can I can strip the file-ending(".php3") out the string?

Thank you in advance - Aviv Revach
