Multidimensional array remove values

If I have a multdimensional array like so:

$records = array(
array('product' ='30 year','rate'=6.0 'ProgramID' =>9514),
array('product' ='30 year','rate'=6.0 'ProgramID' =>9514),
array('product' ='30 year','rate'=6.0 'ProgramID' =>9517),
array('product' ='Pay option','rate'=1.0 'ProgramID' =>9513),
array('product' ='Pay option','rate'=1.0 'ProgramID' =>9513));


How could I iterate through this and removing only values that are
duplicated by ProgramID. In this example the new array should contain only
the 1st, 3rd and 4th values. Any help appreciated.

<?php
$records = array(
array('product' ='30 year','rate'=6.0, 'ProgramID' =>9514),
array('product' ='30 year','rate'=6.0, 'ProgramID' =>9514),
array('product' ='30 year','rate'=6.0, 'ProgramID' =>9517),
array('product' ='Pay option','rate'=1.0, 'ProgramID' =>9513),
array('product' ='Pay option','rate'=1.0, 'ProgramID' =>9513));


function remove_dups($array, $row_element) {
$new_array[0] = $array[0];
foreach ($array as $current) {
$add_flag = 1;
foreach ($new_array as $tmp) {
if ($current[$row_element]==$tmp[$row_element]) {
$add_flag = 0; break;
}
}
if ($add_flag) $new_array[] = $current;
}
return $new_array;
} // end function remove_dups

$a = remove_dups($records, 'ProgramID') ;

print_r ($a);

?>

I'll tell you to try and fix the problem in a lower level.
How is this array gennerated ?

The vlaues that are Dups shoul be used as primary keys.

So create something like that $record[$productId][$rate][$programId]

That's how I work... it makes more sense from a Relational point of
view.
