The topic of qualifying in PHP and MySQL development is something I only want to touch on briefly, but nevertheless it is quite important. Zend and MySQL offer certification for PHP and MySQL respectively, which means that if you sit a few tests and pass with sufficiently high marks you can add "Qualified PHP and MySQL developer" to your rÃ©sumÃ©. The exams themselves aren't too hard, and both have study guides to help you brush up on your skills, but you should have at least six months experience using PHP/MySQL before you try them.
If you want to be extra-sure of high marks, you could try taking a course in the topic of your choice - there are training parts around the world that can coach you towards Zend/MySQL certification, and this vastly increases your chances of success.
If this was helpful, please take a moment to tell others about Hacking with PHP by tweeting about it!
