wordpress 中的hook机制,在原生php脚本中如何简洁的表达实现?
wordpress 中的hook(钩子)机制,也就是add_action和do_action这样的组合钩子功能,在原生php脚本中如何来实现?例如有
add_action('main','function1');<br />add_action('main','function2');<br />do_action('main');
这样的功能,在原生php中怎么来简洁的表达实现?
谢谢

$hook = array();<br /><br />function main() {<br /> global $hook;<br /> foreach($hook as $fn) {<br /> if(function_exists($fn)) $fn();<br /> }<br />}
用于没有规则的约束,参数的传递是个问题(太自由了)
一般宜用类实现,比较容易附加约束
