Java类反射应用得非常广泛几乎是所有框架的最核心部分，PHP程序员似乎从不关心反射。尝试着用java的思想去理解php的反射，跟java基本上基本一致。参考了php手册：http://www.php.net/manual/zh/book.reflection.php。
ReflectTest.php:
class ReflectTest {
/**
/**
- 用户名
*/
private $userName;
/**
- 用户密码
*/
private $password;
/**
/**
/**
- 登陆次数
*/
private $loginTimes;
public function ReflectTest(){
}
public function __construct($userId,$userName,$password){
$this->userId = $userId;
$this->userName = $userName;
$this->password = $password;
}
/**
-
- @return the $userId
*/
public function getUserId() {
return $this->userId;
}
/**
-
- @return the $userName
*/
public function getUserName() {
return $this->userName;
}
/**
-
- @return the $password
*/
public function getPassword() {
return $this->password;
}
/**
-
- @return the $email
*/
public function getEmail() {
return $this->email;
}
/**
-
- @return the $qq
*/
public function getQq() {
return $this->qq;
}
/**
-
- @return the $loginTimes
*/
public function getLoginTimes() {
return $this->loginTimes;
}
/**
-
- @param field_type $userId
*/
public function setUserId($userId) {
$this->userId = $userId;
}
/**
-
- @param field_type $userName
*/
public function setUserName($userName) {
$this->userName = $userName;
}
/**
-
- @param field_type $password
*/
public function setPassword($password) {
$this->password = $password;
}
/**
-
- @param field_type $email
*/
public function setEmail($email) {
$this->email = $email;
}
/**
-
- @param field_type $qq
*/
public function setQq($qq) {
$this->qq = $qq;
}
/**
