php 函数可以有关键字参数吗?(像蟒蛇)

问题描述

可能的重复:
命名的 PHP 可选参数?

我想这样做:

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!?");

这样我就可以忽略传递前 2 个参数而只传递我想要的参数.

That way I can ignore passing the first 2 arguments and simply pass the one I want.

这是一个 示例在python中.

Here's an example in python.

推荐答案

不，但是你可以传递一个数组:

No, but you can pass an array:

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