阵列，从数组键中提取值并将它们组合在一起

Question

使用Sencha Touch（对于该问题不重要），将下面的数据数组发送到我的PHP脚本。

["slider3"]  => 1 
["toggle3"]  => 0 
["text3"]  => "text" 
["slider8"]  => 5 
["toggle8"]  => 0 
["text8"]  => "text" 
["slider11"] => 4 
["toggle11"] => 0 
["text11"]  => "text" 
["slider4"]  => 1 
["toggle4"]  => 0 
["text4"]  => "text" 

正如你可以看到阵列是在这个意义上有点“奇怪”不存在像（1 - > 2 - > 3）的逻辑标识符。相反，输入字段的名称（来自Sencha）与添加到此字符串的数字相同。

您在键（3,8,11,4）末尾看到的数字是'数据'的实际ID。

这是我卡住的地方。对于数据的进一步处理欲修补接收阵列另一个数组像这样：

[0] 

    ["questionid"] => 3 (<- Number on the end of the original key) 
    ["toggle"]  =>  value from toggle3 
    ["slider"]  => value from slider3 
    ["text"]  => value form text3 

[1] 

    ["questionid"] => 8 (<- Number on the end of the original key) 
    ["toggle"]  => value from toggle8 
    ["slider"]  => value from slider8 
    ["text"]  => value from text8 

etc. 

或者换句话说，我想组与在所述键的端部相同的ID的数据一起在一个新的数组。

任何人都知道如何解决这个问题？

尝试：

<?php 
$data = array(
    "slider3"  => 1, 
    "toggle3"  => 0, 
    "text3"  => "text", 
    "slider8"  => 5, 
    "toggle8"  => 0, 
    "text8"  => "text", 
    "slider11" => 4, 
    "toggle11" => 0, 
    "text11"  => "text", 
    "slider4"  => 1, 
    "toggle4"  => 0, 
    "text4"  => "text", 
); 

$newData = array(); 
foreach ($data as $entryKey => $entry) { 
    if (preg_match('/^(.+?)(\d+)$/', $entryKey, $matches)) { 
     list(, $key, $id) = $matches; 

     if (!isset($newData[$id])) { 
      $newData[$id] = array(
       'questionid' => $id 
      ); 
     } 

     $newData[$id][$key] = $entry; 
    } 
} 

$newData = array_values($newData); 
print_r($newData); 

输出：

Array 
(
    [0] => Array 
     (
      [questionid] => 3 
      [slider] => 1 
      [toggle] => 0 
      [text] => text 
     ) 

    [1] => Array 
     (
      [questionid] => 8 
      [slider] => 5 
      [toggle] => 0 
      [text] => text 
     ) 

    [2] => Array 
     (
      [questionid] => 11 
      [slider] => 4 
      [toggle] => 0 
      [text] => text 
     ) 

    [3] => Array 
     (
      [questionid] => 4 
      [slider] => 1 
      [toggle] => 0 
      [text] => text 
     ) 

)
