[TYPO3-dev] FYI: comparing execution speed of some php functions

it should be slower. You would have to cache array_keys to a variable to 
gain a bit speed - but even then you would still have the overhead of 
calling array_keys. On the other hand you might save some memory if the 
array contains huge objects compared to iterating the array directly.
