This just reminded me that, I'm a Zend Certified PHP Developer . Those days :))
I always flat-out refused to become a Zend Certified Engineer. I'm perfectly willing to gain a certificate for my actual programming capabilities, but not for how well I can remember details in a manual.
There wasn't all that much about 'remembering useless details from a manual' in it. I've taken the cert twice (5.x and 5.3 IIRC) and in neither case was there much in the way of 'manual trivia'. Far more were scanning a piece of code and being able to determine what the outcome was (error? if so, which one? if not, what's the output?) than haystack/needle issues.
