How do you consistently retrieve the path information from the query in php? (/index.php/foo/bar)

Question

Basically if the user requests:

index.php/foo/bar

I need "/foo/bar" and for

index.php

I need "" or "/"

I couldn't find any information on google because I don't know what this is called (path info got me the pathinfo() function)

I found PHP_SELF returns differently if there is path info than if there is no info

Answer 1

The portion after your file name /index.php is called the path info (see Apache’s AcceptPathInfo directive). You can access that information with the $_SERVER['PATH_INFO'] variable. And if you want the full requested URL path with query, use $_SERVER['REQUEST_URI'].
