Detailed introduction to bidirectional queues
主旨:主要是考数组的函数 array_pop array_push array_pop array_pop() 函数删除数组中的最后一个元素。删除尾部一 array_push array_push() 函数向第一个参数的数组尾部添加一个或多个元素(入栈),然后返回新数组的长度。 该函数等于多次调用 $array[] = $value。 尾部塞入一array_unshift array_shift array_shift() 函数删除数组中第一个元

简介:这篇文章详解python3 deque(双向队列)的详细介绍
3. php 双向队列类
简介:在实际使用中,还可以有输出受限的双向队列(即一个端点允许插入和删除,另一个端点只允许插入的双向队列)和输入受限的双向队列(即一个端点允许插入和删除,另一个端点只允许删除的双向队列)。而如果限定双向队列从某个端点插入的元素只能从该端点删除,则该双向队列就蜕变为两个栈底相邻的栈了。
4. 实现双向队列
简介:class deque{ public $queue = array(); public $length = 0; public function rpop(){ $node = array_pop($this->queue); $this->countque(); return $node; } public function rp ...

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
