Quick example for using array_udiff to do a multi-dimensional diff
Returns values of $arr1 that are not in $arr2
$arr1 = array( array('Bob', 42), array('Phil', 37), array('Frank', 39)
);
$arr2 = array( array('Phil', 37), array('Mark', 45) );
$arr3 = array_udiff($arr1, $arr2, create_function(
'$a,$b',
'return strcmp( implode("", $a), implode("", $b) ); ')
);
print_r($arr3);
Output:
Array
(
[0] => Array
(
[0] => Bob
[1] => 42
)
[2] => Array
(
[0] => Frank
[1] => 39
)
)
