Is using a PHP Function Alias poor performance/Bad practice?

Question

Just out of curiosity,

Does the alias of a built-in PHP function take any more power than the regular function itself.

AKA, does sizeof() take more time than count() to run?

Note to Micro-Optimization Police: Unless there is a HUGE difference, I don't plan on trying to micro-optimize my script. Was just curious.

Note to the 'Just try it yourself' Police: I'm not able to access a PHP environment right now.

It seems that this has also expanded to a 'Best Pratice', as PHP's documentation states that aliases are best not used, and in turn should simply be called via the master function. In this case, that would mean that count() should be used over sizeof().

Answer 1

I'm quite sure that they compile to the same byte-code equivalents, so the answer will be no.
