Multi Array -> Delete double values

[Pinshushka]

Hi folks,

the problem I have is the following. I have a more-dimensional array contaiting different values. One of these values is [street]. What I try to do is to eliminate all double values of [street]. My original array looks like :

Array([0]=>Array([name]=>Test
[street]=>StreetA
[city]=>City)

  [1]=>Array([name]=>Test2
             [street]=>StreetB
             [city]=>City2)

  [2]=>Array([name]=>Test3
             [street]=>StreetA
             [city]=>City3)

  [3]=>Array([name]=>Test4
             [street]=>StreetC
             [city]=>City4)

  [4]=>Array([name]=>Test5
             [street]=>StreetA
             [city]=>City5)
        :
        :

and the result i would like to have is :

Array([0]=>Array([name]=>Test
[street]=>StreetA
[city]=>City)

  [1]=>Array([name]=>Test2
             [street]=>StreetB
             [city]=>City2)

  [2]=>Array([name]=>Test4
             [street]=>StreetC
             [city]=>City4)

I tried out array_unique, array_flip....but without success. Does anyone know a simple solution for this problem. I would prefer a simple function and no foreach.....

Here's a simple but memory intensive method:
Assume $array2d is the array in question

$temp_array = array();
$temp_street_array = array();
foreach ($array2d as $array1d) {
	if (!in_array($array1d['street'], $temp_street_array)) {
		$temp_street_array[] = $array1d['street'];
		$temp_array[] = $array1d;
	}
}
$array2d = $temp_array;

Still, it uses the foreach construct.
I could do without that, of course, but why do extra work?
