$class = new ReflectionClass(‘Person‘);//建立反射
echo ‘<pre>‘;

//导出类
$class->export($class);
//获取类中某个常量的值
echo $class->getConstant(‘ONE‘);   // print "number one"
//获取类中所有常量,数组形式
print_r($class->getConstants());
//获取类中的构造函数 如果类中不存在构造函数则返回 NULL
var_dump($class->getConstructor());
//获取类中的熟悉
var_dump($class->getDefaultProperties());
//获取类的注释(注释格式必须按要求去写)
var_dump($class->getDocComment());
//获取类的最后一行的行数
echo $class->getEndLine();

//其他方法详见  http://php.net/manual/zh/book.reflection.php
