将数组从键/值转换为多维

标签: php arrays cakephp

这似乎是一个相当微不足道的问题,请原谅我的无知。仍然掌握数组操作......

我有一个CakePHP应用程序,它将一个数组发布到我的控制器以进行保存。我需要以某种方式重新格式化已发送的数组,以便可以通过Cake的保存行为正确处理它。

发布的数组是:

Array ( 
        [788] => Array ( [id] => 788 )  
        [787] => Array ( [id] => 787 )  
        [786] => Array ( [id] => 0 )  
        [785] => Array ( [id] => 0 )  

        [value_1] => 0 

        [analysed_date] => Array ( 
           [month] => 08 
           [day] => 16 
           [year] => 2011 
        )  

        [job_id] => 34 
) 

所需数组:

Array ( 
    [0] => Array ( 
        [id] => 788 
        [value_1] => 0 
        [analysed_date] => Array ( 
            [month] => 08 
            [day] => 16 
            [year] => 2011 
        )  
    )  
    [1] => Array ( 
        [id] => 787 
        [value_1] => 0 
        [analysed_date] => Array ( 
            [month] => 08 
            [day] => 16 
            [year] => 2011 
        )  
    )  
)

感谢您花时间去看。


修改

我刚刚意识到我省略了如果数组有[id] =>的事实0它需要被忽略。这是我的主要绊脚石。道歉。我希望编辑能更好地澄清我的问题。

解决

谢谢你的帮助。我能够自己想出解决方案。这就是我想出来的。

foreach($org_array as $key => $value){
    if(is_array($value)){
        if(isset($value['id'])){
            if($value['id'] != 0) {
                $data[$i] = array(
                    'id' => $value['id'],
                    'value_1'=> $value_1,
                    'analysed_date' => $date
                );
                $i++;
            }
        }   
    }
}

这样的事情应该有用,但仅限于你的例子:

$array_keys = array_keys($org_array);
$new_array = array();
foreach ($array_keys as $key)
{
  if (is_int($key))
  {
    $new_array[] = array(
        "id" => $key,
        "value1" => $org_array["value1"],
        "analysed_date" => $org_array["analysed_date"]
      );
    // you might want to loop throught the original array to get all non-integer key values instead of hard-coding it
  }
}

$main = Array ( 
        [788] => Array ( [id] => 788 )  
        [787] => Array ( [id] => 787 )  
        [786] => Array ( [id] => 786 )  
        [785] => Array ( [id] => 785 )  

        [value_1] => 0 

        [analysed_date] => Array ( 
           [month] => 08 
           [day] => 16 
           [year] => 2011 
        )  

        [job_id] => 34 
) 

$analysed_date = $main['analysed_date'];
$value1 = $main['value_1'];

$result = array();
$i=0;
foreach($main as $key=>$value)
{
if( is_numeric($key)
 {
   $result[$i]=array();
   $result[$i]['id']=$key;
   $result[$i]['value_1']=$value1;
   $result[$i]['analysed_date']=$analysed_date;
   $i++;
 }
}
