After recently taking the Zend PHP 5.3 Certification exam, Alexei Shuga has decided to share some of his thoughts on his experience to hopefully give other developers out there a better idea of what was involved.
First of all, the exam is quite complex, yet it's pretty much easy to pass if you're writing PHP code using latest additions like namespaces, late static binding or lambda functions. Even if you do not use these techniques in your code, but you're aware of them and saw PHP syntax for those features (including restrictions like "namespace" keyword proper placement), it would not be a problem for a candidate to pass Zend PHP 5.3 exam.
He includes a few things that could trip you up in the exam including questions one differences in file system functions and some that were just, as he puts it, "stupid." (some were matters of opinion)
