"So, as an example:
A = 1,2,3
B = 2,3,4
should NOT be:
C = 1,4
but:
A = 1
B = 4"
I think you're wrong. This function "Returns an array containing all the entries from
array1 that are not present in any of the other arrays." So you would get C = 1, and NOT C =
1,4.
So you could just do it like that:
<?php
$original = array(1,2,3);
$new = array(2,3,4);
$delete = array_diff($original, $new); // array(1)
$insert = array_diff($new, $original); // array(4)
?>
