函数

函数参数最好少于2个

限制函数参数个数极其重要因为它是你函数测试容易点。有超过3个可选参数参数导致一个爆炸式组合增长,你会有成吨独立参数情形要测试。

无参数是理想情况。1个或2个都可以,最好避免3个。再多旧需要加固了。通常如果你的函数有超过两个参数,说明他多做了一些事。 在参数少的情况里,大多数时候一个高级别对象(数组)作为参数就足够应付。

Bad:

function createMenu($title, $body, $buttonText, $cancellable) {
  // ...
}

Good:

class menuConfig() {
  public $title;
  public $body;
  public $buttonText;
  public $cancellable = false;
}

$config = new MenuConfig();
$config->title = 'Foo';
$config->body = 'Bar';
$config->buttonText = 'Baz';
$config->cancellable = true;

function createMenu(MenuConfig $config) {
  // ...
}
