note 85006 added to function.array-intersect

Regarding array union: Here is a faster version array_union($a, $b) But it is not needed! See below. <?php // $a = 1 2 3 4 $union = // $b = 2 4 5 6 array_merge( $a, array_diff($b, $a) // 5 6 ); // $u = 1 2 3 4 5 6 ?> You get the same result with $a + $b. N.B. for associative array the results of $a+$b and $b+$a are different, I think array_diff_key is used.
