如何不同多維關聯數組內的相同密鑰的值分配給變量

Question

我有此arrray：

Array([memberemailaddress] => Array 
     (
      [id] => memberemailaddress 
      [tag] => {my:memberemailaddress} 
      [label] => Memberemailaddress 
      [callback] => memberemailaddress 
     ) 

    [membertelephonenumber] => Array 
     (
      [id] => membertelephonenumber 
      [tag] => {my:membertelephonenumber} 
      [label] => Membertelephonenumber 
      [callback] => membertelephonenumber 
     ) 

    [officename] => Array 
     (
      [id] => officename 
      [tag] => {my:officename} 
      [label] => Officename 
      [callback] => officename 
     )) 

基本上，內陣列的論文陣列中的每一個（）包含相同的確切鍵。我正在嘗試爲每個「回調」值創建一個函數，以替換下面的foo。

 public function foo() 
    { 

    return 'fooValue'; 
    } 

所需的輸出：

 public function $array[$key]['callback']() 
    { 

    return '$array2[$key]'; 
    } 

這是$數組2：

$data = array(

'@attributes' => array(
    'memberemailaddress' => 'member@gmail.com', 
    'membertelephonenumber' => '555-1212', 
    'officename' => 'Main Street', 

    )); 

所需的輸出...

public function memberemailaddress() 
    { 

    return 'member@gmail.com'; 
    } 

嘗試：

$realKey = ""; 
foreach($array[$key] as $key) {  
    $realKey = $array[$key]; 

} 
    public function ($realKey[$key]['callback'])() { 

return '$array2[$realKey]'; 
} 

如果更容易to follow this，請指教。所有幫助讚賞。

這樣的事情？

function getFoo(array $arr) { 
    return $arr['callback']; 
}
