比较二维数组的元素

Question

我有所有包含数据的几个文件我收集这些数据作为一个二维数组现在我必须veriefie有文件中的数据（file1），如果他们redandante在其他文件中：means （我已经transforemed我的文件数组）例如选项卡[0] [j]与另一个选项卡[i] [j]除与他自我交集（i！= 0） tab [0] [0] =“a” ;标签[0] [1] = “B”;标签[0] [2] = “AC”;标签[0] [3] = “N”;标签[1] [0] = “G”;标签[1] [1] = “A”; tab [1] [2] =“h”;标签[1] [3] = “B”;标签[2] [0] = “GDD”;标签[2] [1] = “A”;标签[2] [2] = “HD”;标签[2] [3] = “B”; 我的程序必须允许我比较始终标签[0] []与他人 我希望我清楚这个时间，感谢您的帮助

$withDuplicates = array(
    array(1,2,3,4), 
    array(1,3,2,4), 
    array(1,2,3,5), 
    array(1,3,2,4), 
    array(1,2,3,4), 
); 

$duplicatesEliminated = array_map(
    'unserialize', 
    array_reduce(
     $withDuplicates, 
     function ($returnArray, $entry) { 
      $serialized = serialize($entry); 
      if (!in_array($serialized, $returnArray)) 
       $returnArray[] = $serialized; 
      return $returnArray; 
     }, 
     array() 
    ) 
); 

var_dump($duplicatesEliminated);
