As Cal Evans mentions in this new post to the Zend Developer Zone, there's a digg-like programming targeted site out there that is "looking to feel the PHP love" - dzone.com.

For those that don't know dzone or Rick, dzone is a social bookmarking site targeted at developers of all languages. Rick Ross is the founder of dzone. Like most social bookmarking sites, on dzone you can post links to articles you like, vote on articles others have posted and leave comments. Unlike bigger sites of this nature, you don't get the latest Apple rumor or > personal political agenda /> story. Everything is 100% developer centric.

Be sure to check out some of the great links they have in their PHP tagged section including:

• Working example of Microformats as an API
• It had to happen: Ruby on Rails opinions from a PHP developer
• True rapid visual application development environment for PHP available

And it's not just for PHP-related information either - there's tons of other tagged goodness to be found.
