如何在多維3D陣列中獲得獨特的價值？

Question

如何從多維數組獲得唯一身份證值？

$arr = array(
    array(
     array("avg"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete"), 
    ), 
    array(
     array("avg","responsecnt"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete"), 
    ), 
    array(
     array("avg","abc"), 
     array("responsecnt","xyz"), 
     "other" => array ("surveycomplete", "yes"), 
    ), 
    array(
     array("avg"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete"), 
    ) 
); 
echo "<pre>"; 
print_r($arr); 
//find unique value 

我需要一些方法來找到上面的數組中的唯一值。有人能幫我嗎？

運行這個腳本，我想你會看到如何做你想做的事情。

<?php 
$arr = array(
    array(
     array("avg"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete") 
    ), 
    array(
     array("avg","responsecnt"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete") 
    ), 
    array(
     array("avg","abc"), 
     array("responsecnt","xyz"), 
     "other" => array ("surveycomplete", "yes"), 
    ), 
    array(
     array("avg"), 
     array("responsecnt"), 
     "other" => array ("surveycomplete"), 
    ) 
); 
echo "<pre>"; 
print_r($arr); 

for($i=0;$i<sizeof($arr);$i++){ 
    for($j=0;$j<sizeof($arr[$i]);$j++){ 
     for($k=0;$k<sizeof($arr[$i][$j]);$k++){ 
      echo $arr[$i][$j][$k]."<br>"; 
     } 
    } 
    for($l=0;$l<sizeof($arr[$i]["other"]);$l++) 
    {echo $arr[$i]["other"][$l]."<br>";} 
}
