RegAxe was created as a handy and open source instrument that can help you test Java and PHP regular expressions.
You can use RegAxe to paste / type Java or PHP style formatted regular expressions and they will be automatically converted before executing the test.

Here are some key features of "RegAxe":
· Mouse over matches shows match groups
· Highlights invalid RegExp
· RegExp options (global, ignore-case, single-/multiline, replace)
· Automatically re-tests if text or RegExp is changed
· Generate RegExp from HTML
