foreach (get_declared_classes() as $class){
$reflectionClass = new ReflectionClass($class);

$items = $reflectionMethod->invoke($pluginInstance);
}

function computeArticles(){
$articles = array();

}
}
return $articles;
}
require_once('plugin.php');
$menu = computeMenu();
$articles = computeArticles();
print_r($menu);
print_r($articles);
//plugin.php 代码如下
class MycoolPugin implements Iplugin {
public static function getName(){
return 'MycoolPlugin';
}
public static function getMenuItems(){
return array(array('description'=>'MycoolPlugin','link'=>'/MyCoolPlugin'));
}
public static function getArticles(){
return array(array('path'=>'/MycoolPlugin','title'=>'This is a really cool article','text'=>xxxxxxxxx));
}
}上述代码是php反射类的一个应用。
什么是php反射类,顾名思义,可以理解为一个类的映射。
举个例子:
class fuc { //定义一个类
static function ec() {
echo '我是一个类';
}
}
$class=new ReflectionClass('fuc'); //建立 fuc这个类的反射类
至于$class 这反射类里有什么东东,可以查看手册,这里不详解了
$fuc=$class->newInstance(); //相当于实例化 fuc 类
$fuc->ec(); //执行 fuc 里的方法ec
其中还有一些更高级的用法
$ec=$class->getmethod('ec'); //获取fuc 类中的ec方法
$fuc=$class->newInstance(); //实例化
$ec->invoke($fuc); //执行ec 方法
上面的过程很熟悉吧。其实和调用对象的方法类似
只不过这里是反着来的,方法在前,对象在后
