Hi, I am not too much in array_unique() but played with array_diff() for a week to implement array_diff_assoc() with no success so far but atm I am dreaming the code of array_diff. I saw that most of the code of array_diff() is in array_intersect() and probably in array_unique() (yup it is like them). The argument is sorted with zend_qsort() by value and nothing is known for the key order in the sorted array. Then the array is traversed from the beginning to the end and when two or more sequental elements are equal everything starting the second equal is wiped (in the result that is returned).
