array Set::pushDiff ($array1, $array2)

This function merges two arrays and pushes the differences in array2 to the bottom of the resultant array.

$array1 = array('ModelOne' => array('id'=>1001, 'field_one'=>'a1.m1.f1', 'field_two'=>'a1.m1.f2'));
$array2 = array('ModelOne' => array('id'=>1003, 'field_one'=>'a3.m1.f1', 'field_two'=>'a3.m1.f2', 'field_three'=>'a3.m1.f3'));
$res = Set::pushDiff($array1, $array2);

/* $res now looks like: 
	Array
	(
	    [ModelOne] => Array
	        (
	            [id] => 1001
