從多維數組中獲取值並存儲到關聯數組中

我想通過循環以下多元數組來將所有員工的工資存儲爲$ salary數組。從多維數組中獲取值並存儲到關聯數組中

任何人都可以幫助我嗎？謝謝！

<?php 
$employees["employee 1"]["name"] = "Dana"; 
$employees["employee 1"]["title"] = "Owner"; 
$employees["employee 1"]["salary"] = "$60,000"; 

$employees["employee 2"]["name"] = "Matt"; 
$employees["employee 2"]["title"] = "Manager"; 
$employees["employee 2"]["salary"] = "$40,000"; 

$employees["employee 3"]["name"] = "Susan"; 
$employees["employee 3"]["title"] = "Cashier"; 
$employees["employee 3"]["salary"] = "$30,000"; 
?>

，你知道如何循環，你知道如何訪問數組的元素。你有什麼問題？特別是，你正在尋找一個foreach循環。 – Corbin

下面的代碼可以幫助你：

$salary = array(); 
foreach ($employees as $key => $value) { 
    $salary[$key] = $value['salary']; 
}

foreach ($employees as $employee) { 
    foreach ($employee as $var => $val) { 
    $$var[$employee] = $val; 
    } 
}

然後，你應該有三個陣列，$name，$title，$salary。

不是他要求的。（編輯：另外，我傾向於在可能的情況下避免使用變量變量，它們比普通變量更模糊，並且它們很少用於數組不適合的目的。） – Corbin

你可以做到這一點像下面的代碼。

foreach($employees as $key =>$values){ 
    $emp[$key]['name'] = $values['name']; 
    $emp[$key]['sal'] = $values['salary']; 
} 

echo '<pre>'; 
print_r($emp);

出認沽將是：

Array 
(
    [employee 1] => Array 
     (
      [name] => Dana 
      [sal] => $60,000 
     ) 

    [employee 2] => Array 
     (
      [name] => Matt 
      [sal] => $40,000 
     ) 

    [employee 3] => Array 
     (
      [name] => Susan 
      [sal] => $30,000 
     ) 

)

謝謝..根據您的問題
