Deleting multiple entries in an array

[Daggeth]

I have a mult-dimensional array like this:

$array[$variable][1]
$array[$variable][2]
$array[$variable][3]
$array[$variable][4]
$array[$variable][5]

Now $array[$variable][1] contains a unique ID, just some plain numbers. What I need to do is parse through the array, and delete multiple entries with the same ID. I cant figure it out.

I cant seem to use it in a multidimensional aspect like I want to! Any tips?

Sample values:

$array[1][1] = '123'
$array[1][2] = 'subject'
$array[1][3] = 'post'

$array[2][1] = '234'
$array[2][2] = 'subject 3'
$array[2][3] = 'post 3'

$array[3][1] = '123'
$array[3][2] = 'subject 3'
$array[3][3] = 'post 3'

I would need the whole section $array[3] gone, because it has the same ID as $array[1] ...

Yah, I guess it would test if the entire array were unique, not just a leading element. A hack?

function cleanArray($array) {
   $checkarray=array();
   for ($z=0; $z<count($array); $z++)  {
      $checkarray[$z]=$array[$z][1];  // or zero, whatever key you need
      }
   $checkarray=array_unique($checkarray);
   return $checkarray;
   }

Like I said, just a hack. No idea if it'll even help.
