Subject:
FFOTD - Favorite Function of the Day

Body:
http://www.php.net/manual/en/function.array-diff-key.php

array array_diff_key ( array $array1 , array $array2 [, array $... ] )

Here’s the situation:

  • I’m checking to see if the currently logged in user has certain roles to access a page
  • I have 2 arrays, 1) the roles the user has, 2) the roles that they should have for access <= key’s set to the role_id

Instead of running a nested loop to see if the user has those roles, I just use array_diff_key to see what the deltas of the array keys are in both arrays. If there’s a delta, then NO ACCESS. If there’s no delta, then they are all good!

woot!

Anyone wanna go on a double-date with us?
