Eirik Hoem has pointed out an online tool a coworker shared with him to work with regular expressions for multiple languages.

A coworker of mine has been working on a ajax enabled regex tool which lets you evaluate regex expressions in several languages (including PHP PCRE and PHP POSIX) with instant results.

The tool lets you put in the string you want to match again and the pattern you want to match with. The results are automatically populated below it, making it easy to fine-tune your expression to only what you want.

According to this new post on the Zend Developer Zone, its parent company, Zend, has launched their Zend Product Online Documentation Center:

You know when you reach that point when you just don't remember where to configure your Zend Platform Events, how to set up your Tunneling, or what that Zend Core extension does? Well the documentation team at Zend have come up with a way to make all Zend product documentation as easily available as possible, so you can all benefit from our wisdom and experience.

The documentation center is a resource for all things Zendy - information on their products made searchable and easy to browse.
