Array duplicated how to make a single

Question

I have for example var $test and the output is below. You can see its duplicated. How can i make it not duplicated? Is there any function for it?

Array ( 
       [title] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
       [subtitle] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
)    
Array ( 
       [title] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
       [subtitle] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
)

Expected result:

Array ( 
       [title] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
       [subtitle] => Array ( 
             [0] => this field is required 
             [1] => must be longer than2 
       ) 
)

did you at least try [array_unique](http://php.net/manual/en/function.array-unique.php) ? — adeneo, May 19 '13 at 13:57
It's a long shot, but have you tried this one? http://dk1.php.net/manual/en/function.array-unique.php — Nikola, May 19 '13 at 13:57

function intersect($data=NULL){
      if(!empty($data)){$crashed = array();
      $crashed2 = array();
      foreach($data[0] as $key=>$val){ 
             if(!is_array($val)){
               $crashed[$key] = in_array($val,$data[1]);//return true if crashed(intersect)
              }else{
               $crashed2[$key] = intersect(array($val,$data[1]));
              }
      $crashed = array_merge($crashed,$crashed2);
       }
    }return $crashed;
   }
   $intersect =intersect(array($array1,$array2));
   print_r($intersect);

You can use ;

$unique = array_map("unserialize", array_unique(array_map("serialize", $array)));
print_r($unique);
