PHP中的reflection反射機制測試例子_php執行個體

Java類反射應用得非常廣泛幾乎是所有架構的最核心部分，PHP程式員似乎從不關心反射。嘗試著用java的思想去理解php的反射，跟java基本上基本一致。參考了php手冊：http://www.php.net/manual/zh/book.reflection.php。

ReflectTest.php:

<?php class ReflectTest {     /**     * 使用者ID     */    private $userId;     /**     * 使用者名稱     */    private $userName;     /**     * 使用者密碼     */    private $password;     /**     * 使用者郵箱     */    private $email;     /**     * 使用者QQ號碼     */    private $qq;     /**     * 登陸次數     */    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;    }     /**     *     * @param field_type $loginTimes                 */    public function setLoginTimes($loginTimes) {        $this->loginTimes = $loginTimes;    }}?>

Test.php:

<?php  require_once 'ReflectTest.php';  $ref = new ReflectTest("1", "admin", "admin888");//執行個體化ReflectTest  echo "<h1>ReflectTest init.</h1><br/>UserId:".$ref->getUserId()."<br/>UserName:".$ref->getUserName()."<br/>Password:".$ref->getPassword();  $class = new ReflectionClass('ReflectTest');//反射載入ReflectTest類  $instance = $class->newInstanceArgs(array('123','root','123456'));//ReflectTest初始化   echo "<h1>Field:</h1><br/>";  $field = $class->getProperties();  foreach($field as $f) {    echo $f->getName()."<br/>";//反射輸出所有的成員變數  }   echo "<h1>get Fields DocComment:</h1><br/>";  foreach($field as $f) {    $docComment = $f->getDocComment();//反射輸出所有成員變數的文檔注釋    echo $docComment."<br/>";  }   $method = $class->getMethods();//擷取ReflectTest所有方法  echo "<h1>get Methods DocComment:</h1><br/>";  foreach($method as $m) {    $docComment = $m->getDocComment();//擷取所有方法的文檔注釋    echo $docComment."<br/>";   }   echo "<h1>get Methods:</h1><br/>";  foreach($method as $m) {    $k = "get";//只調ReflectTest中的所有的get方法    echo $m->getName()."=".($k === "" || strpos ( $m->getName (), $k ) === 0?$m->invoke($instance):"")."<br/>";    if("setQq"==$m->getName()){      $m->invoke($instance,'441637262');//調用setQq方法為ReflectTest當中的成員變數qq設值    }  }   echo "<h1>Invoke (set/get)Qq result:</h1><br/>";  $qq=$class->getmethod('getQq');//擷取getQq方法  echo "getQQ:".$qq->invoke($instance)."<br/>";//擷取成員變數qq的值  echo "jb51.net";?>

請求http://localhost/php/test/Test.php輸出結果：
