Description:

hi

if I have an undetermined number of array I can't use array_diff to get the differences

a function like: array_diff_array() would be really nice

<?php

$myarrays[] = array("a" => "green", "red", "blue", "red");
$myarrays[] = array("b" => "green", "yellow", "red");
// undetermined number of arrays

print_r(array_diff_array($myarrays));

?>

I think that the only way to do this now, is using eval!

thank you!

I agree, BUT this is opening a big can of worms because there are plenty other functions that could use the same treatment, like array_merge and the likes.

You can already do this using call_user_func_array:

    $diff = call_user_func_array('array_diff', $arrays);
