我发现用@property 申明属性后,类中也可以使用,如下面的代码!请问adminName1和adminName2有什么区别?是不是一般申明属性都用@property?
/**
* @property string adminName1
*/
class test {
private $adminName2;
public function getName($pram1,$pram2) {
$this->adminName1 = $pram1;
$this->adminName2 = $pram2;
}
}
?>
回复讨论(解决方案)
你没看到他是在注释里面的吗?
@property string adminName1
是说属性 adminName1 是一个字符串
这只是为了帮助理解程序的说明文字
我看到他在注释里,知道在其他地方调用的时候可以用于提示信息!我不明白为什么在类里面可以使用它?
你根据它的规则走就是啦。这是出自哪里的代码?
我在yii框架里面看到的。但是我自己写了一个测试,也可以,如下:
/**
* @property string adminName1
*/
class test {
private $adminName2;
public function setName($pram1,$pram2) {
$this->adminName1 = $pram1;
$this->adminName2 = $pram2;
}
public function getName() {
return $result = $this->adminName1." ".$this->adminName2;
}
}
$test = new test();
$test->setName("admin1", "admin2");
echo $test->getName();
?>
//输出结果:admin1 admin2
所以我想php是不是就有这个规则?
已经说了 是为了帮助理解程序的说明文字
像你这样一改
/**
* @property string adminName1
*/
就没有说明的意义了,相反还会产生误解
明明他说有一个 adminName1 属性,我怎么没看到呀?只看到 adminName2,是不是还要定义一个 adminName1 呀
你在说什么?

这位师兄,非常感谢你的回答,但是我觉得你没有明白的我意思!
楼主,我也在找这个问题的答案,回复的几位兄台确实没明白楼主的意思。
没google到答案,我个人的理解,这是给IDE看的,
@property关键字作为转义,IDE遇到这类注释,自动为其加入属性列表(即使它不存在,你可以按这个格式添加一个不存在的属性试试)。
目的是为一些魔术属性变得显式,让调用的开发者更清楚,当然,需要IDE的支持
首先这个标识属性以后,属性还是未被定义,对这些属性的调用最后都是调用__set和__get方法。常见的使用方法是:
public function __get($name){ $getter='get'.$name; if(method_exists($this,$getter))return $this->$getter();}
最后对这些未定义属性的方法都转换为get/set函数的访问。

恩,我觉得你说的有道理,这种属性必须在使用的时候要先赋值,如果没有赋值会警告的。

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
