I just passed Zend Certification exam for PHP 5.3 . It means I have paid Zend, first of all.
They gave me a printed paper (phisical paper) with instruction on what I can do.
It says I can use Zend Certified Engineer icon found in http://www.zend.com/en/services/certification/zce-logo on my CV and site. This is the one that apply to me:
I had 90 minutes to complete the exame task. 70 questions, some multiple, some free text. Really tricky. I used all 90 minutes.
I have no other info about which of my answer is wrong, but I am pretty sure there is at least one or two where I have to remember a particular function and I could have failed.
That's all folk.
