多維數組輸出到foreach循環

Question

我有一個MD數組，我需要運行一個函數來返回結果。 把它放到上下文中，它的5臺服務器有1-3個硬盤，可以獲得剩餘空間。

$array = array(
"Server 1" => array("C" => "85791338496", "D" => "322119397376"), 
"Server 2" => array("C" => "268327448576", "E" => "536733544448", "H" => "274874757120"), 
"Server 3" => array("C" => "42947571712", "E" => "214744166400"), 
"Server 4" => array("C" => "64317550592", "D" => "150320705536"), 
"Server 5" => array("C" => "64317550592") 
); 

它需要遍歷每個服務器，然後每個硬盤驅動器返回可用空間。 這樣做的功能在控制之下，但基於上述數組的循環就是我卡住的地方。

foreach ($array as $server => $disks) { 
    print $server .' has the following disks:'; 
    foreach ($disks as $disk => $avalable_space) { 
     print $disk .' has '. $available_space . 'available space'; 
    } 
}
