可以PHP函數有關鍵字參數？ （如Python）

Question

可能重複：
named PHP optional arguments?

我想這樣做：

function they_said($alice = "", $bob = "", $charlie = "") { 
    echo "Alice said '$alice'"; 
    echo "Bob said '$bob'"; 
    echo "Charlie said '$charlie'"; 
} 

they_said($charlie => "Where are the cookies!?"); 

這樣我可以忽略經過前2個參數，只是通過我想要的那個。

這是python中的example。

沒有，但你可以傳遞一個數組：

function they_said($persons) 
{ 
    foreach ($persons as $person => $text) 
    { 
    echo "$person said '$text'"; 
    } 
} 
they_said(array('charlie' => 'Where are the cookies!?'));
