array_unique for multi-dim arrays?

[Anon]

On my old version of PHP I could use the array_unique function on multi-dimensional arrays, but this no longer works since I upgraded to 4.1.0.

So, whats the best way to strip out duplicate entries in multi-dimensional arrays?

try 4.1.1... they had some array bugs i guess.

I love them arrays i do...

Im always having to write replacement functions in PHP, i had to rewrite array_search the other day because my server PHP build didn't support it

Anyway i wrote this, not saying it cant be improved on of course

<?php

$arr = array(array("1","2","3"),array("3","6","7"));

$unique = make_unique($arr[0],$arr[1]);
var_dump($unique);

function make_unique($v,$c){
  for($k=0; $k < sizeof($v); $k++){
      for($j=0; $j< sizeof($v); $j++){
          if($v[$k] == $c[$j]){
          unset($c[$j]);
          }
      }
  }
  return array_merge($v,$c);
  }

?>

Ive just noticed this algo doesn't really work the same way as array_unique

Hope you can do something with it
