排序/拆分多维阵列​​成许多较小的

Question

更新：对不起，我想通了..我只拿出$值[0]，所以关闭导致其唯一的结果。需要更多的睡眠。非常感谢。我仍然乐于提供建议，以更清晰的方式分割数组。

我有这个结构的阵列$tdata：

Array 
(
    [] => Array 
    (
     [0] => Array 
      (
       [firstName] => test 
       [lastName] => test 
       [userName] => test@test.com 
       [password] => test 
       [course] => test 
       [role] => test 
      ) 

     [1] => Array 
      (
       [firstName] => test 
       [lastName] => test 
       [userName] => test@test.com 
       [password] => test 
       [course] => test 
       [role] => test 
      ) 

    ) 

    [delete] => Array 
    (
     [0] => Array 
      (
       [firstName] => test 
       [lastName] => test 
       [userName] => test@test.com 
       [password] => test 
       [course] => test 
       [role] => test 
      ) 

    ) 

    [update] => Array 
    (
     [0] => Array 
      (
       [firstName] => test 
       [lastName] => test 
       [userName] => test@test.com 
       [password] => test 
       [course] => test 
       [role] => test 
      ) 

    ) 

    [outrole] => Array 
    (
     [0] => Array 
      (
       [firstName] => test 
       [lastName] => test 
       [userName] => test@test.com 
       [password] => test 
       [course] => test 
       [role] => test 
      ) 

    ) 

) 

我想它分割成更小的阵列。像这样：

foreach ($tdata as $key => $value) { 

    if ($key == '') { 
     $create[] = $value[0]; 
    }elseif ($key == 'outrole') { 
     $outrole[] = $value[0]; 
    }elseif ($key == 'delete') { 
     $delete[] = $value[0]; 
    }elseif ($key == 'update') { 
     $update[] = $value[0]; 
    }else{ 
    $noaction[] = $value[0]; 
    } 

} 

这样，数组不断改写自己，我想。 print_r($create)或任何其他数组总是只返回1个结果。可以启发我，告诉我我做错了什么？

如果有更好的方法来做到这一点，我也很乐意听到。

在此先感谢！

Answer 1

如果这些键始终存在，那么你并不真的需要一个循环：

$create = $original['create']; 
$outrole = $original['outrole']; 

如果它们设置您可以添加一个检查：

$create = isset($original['create']) ? $original['create'] : array(); 

如果它不存在，这将设置为空数组。

你的数组是嵌套的。为了让小数组，你应该内在价值内循环：

foreach ($tdata as $key => $value) { 
    if ($key == '') { 
     foreach($value as $subValue) { 
      $create[] = $subValue; 
     } 
    }elseif ($key == 'outrole') { 
     foreach($value as $subValue) { 
      $outrole[] = $subValue; 
     } 
    } // ... and so on...   
}
