As part of manipulating the activity stream, I need to do some precise matching of tags and attributes, so I can remove or manipulate them.
This of course means tasty, tasty regex. The worst part of working with regex is testing your matches (rewrite your expression, upload, refresh, repeat), and I have some tools installed to help with that – however they aren’t all geared towards PHP flavoured Regex.
Which is where this comes in – an online real time, real world PHP regex test utility. It’s great.
