[PHP] array_intersect()

[Chris Lee]

Ok I thought array_intersect() was the function I was looking for, I might
have to write my own.

I want an array with ONLY the keys/values that are present in all the
variables; ie.

<?
    $test_a[] = '974806802083190501';
    $test_a[] = '974806802083190503';
    $test_a[] = '974806802083190504';

    $test_b[] = '974806802083190501';

    $new_array = array_intersect($test_a, $test_b);

    print_r($new_array);
?>

Array
(
    [0] => 974806802083190501
    [1] => 974806802083190503
    [2] => 974806802083190504
)

<?
    $test_a[] = '501';
    $test_a[] = '503';
    $test_a[] = '504';

    $test_b[] = '501';

    $new_array = array_intersect($test_a, $test_b);

    print_r($new_array);
?>

Array
(
    [0] => 501
)

array_insersect() only seems to work with small numbers... or small text.
