PHP ReflectionClass 动态代理

<?php
class mysql
{
    function connect($db)
    {
        echo "连接mysql数据库${db[0]} 
";
    }
}

class oracle
{
    function connect($db)
    {
        echo "连接oracle数据库${db[0]} 
";
    }
}

class sqlproxy
{
    private $target;

    function __construct($tar)
    {
        $this->target[] = new $tar();
    }

    function __call($name, $args)
    {
        foreach ($this->target as $obj) {
            $r = new ReflectionClass($obj);
            if ($method = $r->getMethod($name)) {//获得类的反射方法
                if ($method->isPublic() && !$method->isAbstract()) {
                    $method->invoke($obj, $args);//调用对象的反射方法
                }
            }
        }
    }
}

$mysql = new sqlproxy('mysql');
$mysql->connect('member');

$oracle = new sqlproxy('oracle');
$oracle->connect('member');
