php - which is best array_search or in_array?

Question

I have a large while loop function, every time it gets loaded for check with current URL name. So I need to know which one is better to check the URL name in large array within the while loop, in_array() or array_search() function.

Answer 1

If it's a large array and in a loop, neither is "best". Instead use array_flip() on your array, so urls become keys. And use isset() to check for the presence.
