有不同的名稱環路$ _ POST變量

Question

如何用不同的名字環$ _ POST變量，從print_r的輸出這樣的：

帖子：

$_POST['post_access_1']; 
$_POST['post_access_2']; 
$_POST['post_access_3']; 
$_POST['post_access_4']; 

Array 
(
    [post_access_1] = Array 
     (
      [0] = 1 
      [1] = 6 
     ) 

    [post_access_2] = Array 
     (
      [0] = 1 
      [1] = 4 
     ) 

    [post_access_3] = Array 
     (
      [0] = 2 
      [1] = 5 
      [2] = 6 
     ) 

    [post_access_4] = Array 
     (
      [0] = 2 
      [1] = 5 
     ) 
) 

其中

1 => 1,6 
    2 => 1,4 
    3 => 2,5,6 
    4 => 2,5 

我有搜索並看到，但沒有與不同的名稱。

你可以做這樣的POST變量foreach循環。

foreach ($_POST as $key => $value){ 
    if (is_array($value)){ 
     echo $key ." Is an array in post."; 
     foreach ($value as $k => $v){ 
      echo $k." is the index and ".$v." is the value in the array."; 
     } 
    } 
} 

Answer 2

隨着foreach。

foreach ($array as $foo) 
{ 
// do something with $foo 
} 

如果您需要訪問的鍵/子陣的名稱，以及：

foreach ($array as $k => $v) 
{ 
// do something with $k and or $v 
}
