Edit Question
Title
Body
I would like to check if my array has any duplicates and return the duplicated values in an array. I want this to be as efficient as possible. Example: $array = array( 1, 2, 2, 4, 5 ); function return_dup($array); // should return 2 $array2 = array( 1, 2, 1, 2, 5 ); function return_dup($array2); // should return an array with 1,2 Also the initial array is always 5 positions long
