I'm working on an engine for my website. It's set up to use meta tags that PHP code then handles and creates the page, making it simple to create pages. I know a lot of people may think this is a bad way of processing things, but it's using dynamic paging to load pages. It will essentially load something like load.php?url=home, for example. Then load.php constructs the page if it exists on the server, if not we kill the page and result our 404.
The problem is, I'm using preg_replace() right now to get the value that is contained in the meta tags. This returns the page's PHP code.
All I want to do is get the result and then make the result a variable. I tried preg_filter() but that didn't seem to do anything.
You probably want preg_match and use the $matches array.
