The reflection reflection mechanism test example in PHP, phpreflection

Java class reflection is applied very broadly to almost all of the core parts of the framework, and PHP programmers seem to never care about reflection. Trying to understand PHP's reflection in Java is basically consistent with Java. Refer to the PHP Manual: http://www.php.net/manual/zh/book.reflection.php.

reflecttest.php:

<?php class Reflecttest {/** * User ID */private $userId;     /** * User name */private $userName;     /** * User Password */private $password;     /** * User Mailbox */private $email;     /** * User QQ number */private $qq;     /** * Number of landing times */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->logintim    Es }/** * * @param field_type $userId */Public Function Setuserid ($userId) {$this-&G    T;userid = $userId; }/** * * @param field_type $userName */Public Function Setusername ($userName) {$thi    S->username = $userName; }/** * * @param field_type $password */Public Function SetPassword ($password) {$thi    S->password = $password; }/** * * @param field_type $email */Public Function Setemail ($email) {$this->emai    L = $email;    }/** * * @param field_type $QQ */Public Function setqq ($QQ) {$this->qq = $qq; }/** * * @param field_type $loginTiMES */Public Function setlogintimes ($loginTimes) {$this->logintimes = $loginTimes; }}?>

A detailed explanation of Java Reflection (Java reflection) mechanism

It's starting to pour out again, is it interesting?

What is the reflection mechanism of PHP

can also be called mappings. To be straightforward, not only can he clone objects, but the variables that can invoke the object are very

To the method, quite powerful. PHP API5 with an explanation of the object, there is a chance to look down, similar to

In Java. Of course, this feature is enough to prove that PHP and ASP still have a very big difference!
