Re: [Phpmyadmin-devel] Is PMA_STR_binarySearchInArr needed?

Hi,

For some time I was curious whether PMA_STR_binarySearchInArr is needed at all, and my test showed that there are faster (sometimes much faster) alternatives. Test for 100 000 iterations on PHP 5.3.4 (Windows, i5 2,53 GHz core):

PMA_STR_binarySearchInArr: 2.6606s array_search: 1.8936s isset: 0.0102s array_key_exists: 0.0934s

Isset and array_key_exists require flipped array, but array_search is a drop-in replacement that works faster, even though it does a linear search. Code used to perform this test is at [1].

Looking for different strings gives me different results. For example, looking for "BOTH" and array_search() is faster that PMA_STR_binarySearchInArr().
