我試圖提取通過以下SOAP請求從vCenter Server中提取的虛擬機名稱。雖然我得到了結果（請參閱下面的var_dump），但我無法弄清楚如何在循環中獲取名稱，因爲有許多嵌入式數組，而我嘗試的所有內容都會返回錯誤或數組。我很欣賞這可能是一個相當簡單的，但我無法弄清楚。PHP從嵌套數組中提取值並將其置於循環中以回顯值
這是在我試圖得到的代碼提取下面的名稱值。
$request->specSet = array (
'propSet' => array (
array ('type' => 'VirtualMachine', 'all' => 0, 'pathSet' => array('name','runtime.powerState', 'config.hardware.numCPU', 'config.hardware.memoryMB')),
),
