This article describes the common rules of Yii rules. Share it with everyone for your reference, the details are as follows:
public function rules() { return array( //必须填写 array('email, username, password,agree,verifyPassword,verifyCode', 'required'), //检查用户名是否重复 array('email','unique','message'=>'用户名已占用'), //用户输入最大的字符限制 array('email, username', 'length', 'max'=>64), //限制用户最小长度和最大长度 array('username', 'length', 'max'=>7, 'min'=>2, 'tooLong'=>'用户名请输入长度为4-14个字符', 'tooShort'=>'用户名请输入长度为2-7个字'), //限制密码最小长度和最大长度 array('password', 'length', 'max'=>22, 'min'=>6, 'tooLong'=>'密码请输入长度为6-22位字符', 'tooShort'=>'密码请输入长度为6-22位字符'), //判断用户输入的是否是邮件 array('email','email','message'=>'邮箱格式错误'), //检查用户输入的密码是否是一样的 array('verifyPassword', 'compare', 'compareAttribute'=>'password', 'message'=>'请再输入确认密码'), //检查用户是否同意协议条款 array('agree', 'required', 'requiredValue'=>true,'message'=>'请确认是否同意隐私权协议条款'), //判断是否是日期格式 array('created', 'date', 'format'=>'yyyy/MM/dd/ HH:mm:ss'), //判断是否包含输入的字符 array('superuser', 'in', 'range' => array(0, 1)), //正则验证器: array('name','match','pattern'=>'/^[a-z0-9\-_]+$/'), //数字验证器: array('id', 'numerical', 'min'=>1, 'max'=>10, 'integerOnly'=>true), //类型验证 integer,float,string,array,date,time,datetime array('created', 'type', 'datetime'), //文件验证: array('filename', 'file', 'allowEmpty'=>true, 'types'=>'zip, rar, xls, pdf, ppt','tooLarge'=>'图片不要超过800K'), array('url', 'file', //定义为file类型 'allowEmpty'=>true, 'types'=>'jpg,png,gif,doc,docx,pdf,xls,xlsx,zip,rar,ppt,pptx', //上传文件的类型 'maxSize'=>1024*1024*10, //上传大小限制,注意不是php.ini中的上传文件大小 'tooLarge'=>'文件大于10M,上传失败!请上传小于10M的文件!' ), }); $news= new news('search'); //search关联规则

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
