Question

I would like to know how to create a php function that can be installed in php
just like the already built in functions like :

rename
copy 

The main point I would like to achieve is a simple php function that can be called from ANY php page on the whole host without needing to have a php function within the php page / needing an include.

so simply I would like to create a function that will work like this :

location();

That without a given input string will output the current location of the file via echo etc

As others have said, there’s probably an easier, better way to do most things. But if you want to write an extension, try these links:
