The Voices of the ElePHPant podcast, hosted by PHP community member Cal Evans, has posted the latest in their series of interviews with a member of the PHP community. In this new show Cal talks with Michael Moussa.

Cal and Michael talk about his session at this year's Sunshine PHP conference covering graph databases. He talks about the Neo4j database (the most popular graph database right now) and what kinds of functionality exists for integrating it with PHP. They also talk about a hobby that Michael has: brewing his own beer. He talks about how he got into it and how he's advanced in his methods (and that he's entered in competitions too).
