php函数有关键字参数吗？(比如python)

Question

可能重复:
命名PHP可选参数？

我想做这个:

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!?");

这样我就可以忽略传递前两个参数并简单地传递我想要的那个.

这是python中的一个例子.

不,但你可以传递一个数组:

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