[PHP] What am I missing here?

[Rick Dwyer]

Hello List.

I am completely at a loss for why the line of code below returns the  
desired value:

$PATH_INFO= substr($_SERVER['REQUEST_URI'],strlen($_SERVER['SCRI
PT_NAME']), strlen($_SERVER['REQUEST_URI']));

BUT, putting the same line of code on 1 line fails to return anything:

$PATH_INFO=  
substr($_SERVER['REQUEST_URI'],strlen($_SERVER['SCRIPT_NAME']),  
strlen($_SERVER['REQUEST_URI']));
