How can you make a multidimensional array unique?

Question

I\'ve got a multidimensional array setup like the following:

array(
  [0]=>
  array(
    [\"name\"]=> \"Foo\"
    [\"slug\"]=> \"Bar\"
  )
  [1]=>         


        

Answer 1

You can use an associative array.

$temp_array = array();
foreach ($array as &$v) {
    if (!isset($temp_array[$v['name']]))
        $temp_array[$v['name']] =& $v;
}

This creates a temporary array, using $v['name'] as the key. If there is already an element with the same key, it is not added to the temporary array.

You can convert the associative array back to a sequential array, using

$array = array_values($temp_array);
