Re: Re: Extracting multi dimensional array value

Sorting is definitely slower than going through once c or php. The speed of the algorithm is always more important than the language. There may be a slow down with php but it will always be O(1) and that is negligible. So unless you have only 2 items in the list where only 2 permutations are possible sorting will be slower. min() or max() are the functions to use if possible. for each is a language construct and should be having c like performance. C is not always faster. It's not a magic silver bullet to increase performance. Yes, you probably have fewer machine instructions on most things and don't get me wrong, I love c but if the algorithm is slower c can be slower than php.
