3、简单的例子

<?php
require 'vendor/autoload.php';

class Test
{
    use Lackone\Event;

    public static function call0()
    {
        //获取参数
        var_dump(func_get_args());
    }

    public static function call1()
    {
        echo 'call1...<br>';
    }

    public static function call2()
    {
        echo 'call2...<br>';
    }

    public static function call3()
    {
        echo 'call3...<br>';
    }
}

//绑定事件
Test::on('test', ['Test', 'call0']);
//触发事件
Test::trigger('test', ['hello', 'world']);

echo '



';

//设置事件优先级，优先级越大，越先执行
Test::on('pro', ['Test', 'call1'], 1);
Test::on('pro', ['Test', 'call2'], 2);
Test::on('pro', ['Test', 'call3'], 3);
Test::trigger('pro');

echo '



';

//设置一次性事件，只能触发一次
Test::once('one', ['Test', 'call1']);
Test::trigger('one');
Test::trigger('one');

echo '



';

//解绑事件
Test::on('off', ['Test', 'call1']);
Test::on('off', ['Test', 'call2']);
Test::on('off', ['Test', 'call3']);
//解绑具体的某个回调
Test::off('off', ['Test', 'call2']);
Test::trigger('off');
