어레이를 복제하는 방법

Question

예를 들어 var $ test가 있고 출력이 아래에 있습니다. 복제본을 볼 수 있습니다. 중복되지 않도록하려면 어떻게해야합니까? 거기에 어떤 기능이 있습니까?

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 
     ) 
)  

예상 결과 :

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 
     ) 
)  

Answer 1

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); 

Answer 2

당신은 사용할 수 있습니다;

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