I'm trying to to set the function $request to (in the url) what is after / and minus the last 4 characters. SO if it was mysite. com/red-fish.php gives me "red fish"

This works to explode and remove the dash

PHP Code:

<?php    
$request = $_SERVER['REQUEST_URI'];    
$request = explode('/',$request);    
$_REQUEST['site_search'] = str_replace("-", " ", $request[sizeOf($request)-1]); ?>

But I'm not sure how to knock the .php of the end. This didn't work.

PHP Code:

<?php    
$request = $_SERVER['REQUEST_URI'];    
$request = explode('/',$request);    
$request = substr($request, 0, -4);    
$_REQUEST['site_search'] = str_replace("-", " ", $request[sizeOf($request)-1]); ?>

Your code isn't working because you're trying to take the substr of an array. (explode returns an array)

This should work:

PHP Code:

$request = $_SERVER['REQUEST_URI'];    
$request = strrchr($request,'/');
$request = substr($request, 1, -4); 


Thanks Insensus for pointing out a basic concept I was missing. (Well honestly I was just guessing. Amazing how often that works out for me.) With a bit of other tweaking it's doing the job now.

There is a much easier way:

$request = basename($_SERVER['PHP_SELF'], '.php');
