I'm finding this one hard to approach...

I have a two-dimensional array, containing customer contact information. Looks like:

$myarray[0][0] = "Microsoft";
$myarray[0][1] = "Bill";
$myarray[0][2] = "123-1234";

$myarray[1][0] = "Apple";
$myarray[1][1] = "Steve";
$myarray[1][2] = "456-1234"; <<<<<

$myarray[2][0] = "Oracle";
$myarray[2][1] = "Larry";
$myarray[2][2] = "987-4321";

$myarray[3][0] = "Pixar";
$myarray[3][1] = "Steve";
$myarray[3][2] = "456-1234"; <<<<<

What I want to do is remove records that have the same fax number, so that each fax number occurs only once. For example, $myarray[1][2] and $myarray[3][2] are the same--I would like to remove/unset one of them.

I know that array_unique() will do this for one-dimensional arrays, but I'm kinda stuck here, since the repeating element is in the second dimension. Any ideas how I might do this?
