Padraic Brady has pointed out the "new kid in town" when it comes to magazines about PHP - Enterprise PHP:

There is a new PHP magazine called "Enterprise PHP" available in English, German and French which might even console those missing the apparently ill-fated International PHP Magazine. Back before publication the usual tree of suspects led me to being interviewed for the initial edition published a short while back.

The current issue (which you can get for free after a survey) has articles looking at testing your PHP scripts, how "professional" it is to use PHP and the fact that Java is not PHP (wait, isn't that backwards?)

Aaron Wormus has dug up some old notes that he made at the International PHP Conference back in 2005 on the topic of Unicode in PHP that he wanted to share.

He mentions:

• A case study of an online survey generator
• info about Unicoding and UTF-8
• Iconv and mbstring
• and the migration of the application to support Unicoded characters (a nine step process)

And also, a word of warning:

Everything was much more complex than expected. Don't do this because you think that UTF-8 is cool, it's difficult, not well supported in PHP, and don't do it without needing it. Don't do this without a CVS.
