Look at array_diff() (http://php.net/array_diff). That ought to do what you want.
Yes! Thank you :)

Hi -
I have two arrays that need to be compared. I need to know if their values match or not.
Currently I have:
$array1 = array(a, b, c, d); $array2 = array(c, d, e, f, g);
$intersect = array_intersect($array1,$array2); $num1 = count($array1); $num2 = count($intersect);
Then I can compare $num1 to $num2 to see where I stand on the comparison. Less than, greater than, or equal.
Only there's a problem with this if there are identical values in an array:
$array1 = array(e, e); $array2 = array(c, d, e, f, g);
The intersect for this returns e twice instead of the once that I need for my code. It's true that in array1 there was indeed two matches, but in array2 there was only 1 match, and that is the match that matters in my code. Does this make sense?
Is there a way to do this that I'm missing...?
