Sorry, my regex is a lil rusty! Thanks in advance, ~Phil

That regex might not always work for you, (&amp;) comes to mind. You might want to look at parse_str() which you can use after parse_url() if needed.

I think /(.*)\.php\?action=([^&]+(?(&)[^&+]+))/ might be a step in the right direction for RegExing the additional URL query string parameters. I haven't tested it... but either way, I thought it was worth mentioning that the ".php" part should be "\.php" (or "[.]php"), otherwise it will match "any character followed by php."

Good call! I so passed over that one. ;) Thanks, ~Philip
