I got 10 mock exams with a voucher and I wanted to do that in January 2009. So I started to prepare myself with testing tools, books and manual. You even can see my mock exams progress. But I've stopped that in a middle and this summer I decided to get this done.
So now, I'm officially Zend Certified Engineer (certificate details) born in Russia, living in Israel ;-)
Resources that can help you to reduce holes in you PHP knowledge:
- Zend PHP 5 Certification, Study Guide - must to read
- Zend PHP Certification Practice Test Book (PHP 4) - old test and answers, helped me with streams and PDO
- Guide to PHP Design Patterns
- and, of course, PHP manual with user comments (they sometimes very useful).
