从php中的索引数组创建一个关联的多维数组

问题描述：

I have an array which currently looks like this: its from a form with names like name="buyer_id[]"

Array ( 
   [product_id] => 
      Array ( 
       [0] => 1 
       [1] => 2 
       [2] => 4 
           ) 
   [name] => 
     Array ( 
      [0] => Paper Choco 
      [1] => Paper Fan Vanilla 
      [2] => Pink Prom 
           ) 
  [staff_id] => 
    Array ( 
      [0] => 1 
      [1] => 1 
      [2] => 1 
          ) 
  [category] => 
    Array ( 
      [0] => agent 
      [1] => agent 
      [2] => agent 
         ) 
  [date] => 
    Array ( 
      [0] => 2014-08-22 
      [1] => 2014-08-22 
      [2] => 2014-08-22 
         ) 
  [price] => 
    Array ( 
      [0] => 188 
      [1] => 887 
      [2] => 17 
         )

Now i want it to look like the array below so i can pass it into database:

   array(
     array(
      'product_id' => 1 ,
      'name' => 'Paper Choco',
      'category'=>'agent',
      'staff_id'=> 1,
      'date'=> '2014-08-22'
),
   array(
      'product_id' => 2 ,
      'name' => 'Paper Fan Vanilla ',
      'category'=>'agent',
      'staff_id'=> 1,
      'date'=> '2014-08-22'
),
   array(
      'product_id' => 4 ,
      'name' => 'Pink Prom ',
      'category'=>'agent',
      'staff_id'=> 1,
      'date'=> '2014-08-22'
)
);

I believe this is very much possible but i can not figure a way around it yet

我有一个目前如下所示的数组：来自名称如name =“buyer_id []的表单 “ p>

 数组（
 [product_id] =＆gt; 
数组（
 [0] =＆gt; 1 
 [1] =＆gt; 2 
 [  2] =＆gt; 4 
）
 [名称] =＆gt; 
数组（
 [0] =＆gt; Paper Choco 
 [1] =＆gt; Paper Fan Vanilla 
 [2] =＆gt;  Pink Prom 
）
 [staff_id] =＆gt; 
数组（
 [0] =＆gt; 1 
 [1] =＆gt; 1 
 [2] =＆gt; 1 
）
 [  category] =＆gt; 
数组（
 [0] =＆gt; agent 
 [1] =＆gt; agent 
 [2] =＆gt; agent 
）
 [date] =＆gt; 
数组 （
 [0] =＆gt; 2014-08-22 
 [1] =＆gt; 2014-08-22 
 [2] =＆gt; 2014-08-22 
）
 [price] =＆gt  ; 
数组（
 [0] =＆gt; 188 
 [1] =＆gt; 887 
 [2] =＆gt; 17 
）
  code>  pre> 
 
 现在我希望它看起来像下面的数组，所以我可以将它传递到数据库 ： p> 
 
   array（
 array（
'product_id'=＆gt;  1，
'name'=＆gt;  'Paper Choco'，
'category'=＆gt;'agent'，
'staff_id'=＆gt;  1，
'date'=＆gt;  '2014-08-22'
），
 array（
'product_id'=＆gt; 2，
'name'=＆gt;'Paper Fan Vanilla'，
'category'=＆gt;'agent'  ，
'staff_id'=＆gt; 1，
'日期'=＆gt;'2014-08-22'
），
数组（
'product_id'=＆gt; 4，
'name'=  ＆gt;'粉红色舞会'，
'类别'=＆gt;'代理'，
'staff_id'=＆gt; 1，
'日期'=＆gt;'2014-08-22'
）
）  ; 
  code>  pre> 
 
 我相信这很有可能，但我无法想办法呢 p> 
  div>

答

$result = array();
foreach ($array as $key => $subarray) {
    foreach ($subarray as $i => $value) {
        if (!isset($result[$i])) {
            $result[$i] = array();
        }
        $result[$i][$key] = $value;
    }
}

As an alternative:

$data = array ( 
    'product_id' => array ( 1, 2, 4 ),
    'name' => array ( 'Paper Choco', 'Paper Fan Vanilla', 'Pink Prom' ),
    'staff_id' => array ( 1, 1, 1 ),
    'category' => array ( 'agent', 'agent', 'agent', ),
    'date' => array ('2014-08-22', '2014-08-22', '2014-08-22' ),
    'price' => array ( 188, 887, 17 ),
);

function transpose($array) {
    array_unshift($array, null);
    return call_user_func_array('array_map', $array);
}

$result = transpose($data);
array_walk(
    $result,
    function (&$value) use ($data) {
        $value = array_combine(array_keys($data), $value);
    }
);

var_dump($result);
