you could use a combination of intersect, diff, and merge like this:

PHP Code:


			
<?php
$arr1 = array(array("timestamp" => "2009-10-23", "key_one" => 45));
$arr2 = array(array("timestamp" => "2009-10-23", "another_key" => 1234));
print_r($arr1);
echo "<br /><br />";
print_r($arr2);
echo "<br /><br />";


$identical = array_intersect($arr1[0], $arr2[0]);
$diff = array_merge(array_diff($arr1[0], $arr2[0]), array_diff($arr2[0], $arr1[0]));
$merge[0] = array_merge($identical, $diff);
print_r($merge);
echo "<br /><br />";
?>

this solution just takes into account only 2 arrays, but it can be modified to do for multiple.
