基於鍵陣列的php刪除元素

Question

我有一個多維數組和一個數組，它擁有多維數組中的某個元素的鍵。我怎麼能取消設置該元素，基於數組與鍵。我正在尋找可以工作的代碼，而不管數組的大小。

這裏是例如：

<?php 
$array = array(
    1 => array('name' => 'mike','age' => 23), 
    2 => array('name' => 'nick','age' => 18), 
); 

$keys = array(2,'name'); 

// 
//Here code to unset that element 
// 

/* 
//This is how the new array should be: 
$array = array(
    1 => array('name' => 'mike','age' => 23), 
    2 => array('age' => 18), 
); 
*/ 
?> 

編輯：上面的代碼是用於clearity。我可以添加我迄今爲止嘗試過的unset（），但它沒有任何有用的東西，並且會使問題不太清楚。我要求提供正確方向的提示，而不是完全有效的代碼。

Answer 1

我已經找到了解決方案：

<?php 

function unsetByKeys($keys,&$array,$path = array()){ 

    $diff = count($keys)-count($path); 
    if($diff > 1){ 
     $path[] = $keys[count($path)]; 
     unsetByKeys($keys,$array,$path); 
    }else{ 
     $lastKey = $keys[count($path)]; 

     $subArray = &$array; 
     foreach($path AS $p){ 
      $subArray = &$subArray[$p]; 
     } 
     unset($subArray[$lastKey]); 
    } 
} 

$array = array(
    1 => array('name' => 'mike','age' => 23), 
    2 => array('name' => 'nick','age' => 18), 
); 

$keys = array(2,'name'); 

unsetByKeys($keys,$array); 

var_dump($array); 
?> 

Answer 2

代碼：（http://www.tehplayground.com/#9Oup7h6gh）

// example code 

$array = array(
1 => array('name' => 'mike','age' => 23), 
2 => array('name' => 'nick','age' => 18), 
); 

$keys = array(2,'name'); 

unset($array[($keys[0])][($keys[1])]); 

print_r($array); 

/* 
//This is how the new array should be: 
$array = array(
    1 => array('name' => 'mike','age' => 23), 
    2 => array('age' => 18), 
); 
*/ 

OUTPUT：

Array 
(
[1] => Array 
    (
     [name] => mike 
     [age] => 23 
    ) 

[2] => Array 
    (
     [age] => 18 
    ) 

)
