How can I combine two 2-dimensional arrays into a single array using a
matching key value. Here's an example:

I have these two arrays:

$arr1 = array(
array('key'=>7, 'first_name'=>'Joe'),
array('key'=>14, 'first_name'=>'Susan')
);
$arr2 = array(
array('key'=>14, 'last_name'=>'Doe'),
array('key'=>7, 'last_name'=>'Anderson')
);

I want to create a second array JOINing the two based on the key
value, giving me:

$resulting_arr = array(
array('key'=>7, 'first_name'=>'Joe','last_name'=>'Anderson'),
array('key'=>14, 'first_name'=>'Susan','last_name'=>'Doe')
);

Thanks!

Mike
