php

Generally PHP''s array_*() functions are all very efficient. On a small array, I generally prefer to use a few single action array_* functions if I can avoid loops. But if your mysqli_result is large you may not want to compile it all into an array at once then call array_values(). Instead you may be better to append rows to an array while fetching.
