Getting a file address

[Xu Wei Jie]

I have a question. Wonder if you all can help.

 

If I have a php script "a" that uses system to call php script "b"

i.e.

<?php
system("php b.php",$retval);
?>

 

How do I get script a's file and directory address using php ? Any idea? I need to know this to manipulate relative addresses involved with the calling script. TIA

 

Note: getting the current working address won't work because I can be invoking script a with a relative address.

What do you mean by "script's address?"

Actually I found a solution @ http://www.plus2net.com/php_tutorial/script-self.php

 

However, it still does not work for me as I cannot incrementally build a path based on the trace of the calling scripts. This method only let me retrieve the current calling script's file name and directory address which was what I meant. However, it does not let me know about the the address of previous calling script that calls the current calling script and etc. Hope you are not lost.
