Detailed explanation of PHP Swoole high-performance framework
Swoole is a concurrency framework based on PHP coroutines, which has the advantages of high concurrency processing capabilities, low resource consumption, and simplified code development. Its main features include: coroutine concurrency, event-driven networks and concurrent data structures. By using the Swoole framework, developers can greatly improve the performance and throughput of web applications to meet the needs of high-concurrency scenarios.
Detailed explanation of PHP Swoole high-performance framework
Introduction
Swoole is a coroutine based on the PHP language Concurrency framework can greatly improve the performance of web applications. It has built-in efficient coroutine scheduler, event-driven network engine and concurrent data structure, and can handle a large number of concurrent connections at the same time.
Main features
- Coroutine concurrency: Allows multiple coroutines to execute tasks at the same time to avoid the performance overhead caused by thread switching .
- Event-driven network: Based on efficient event loops such as epoll/kqueue, there is no need to block and wait when processing network requests.
- Concurrent data structure: Provide high-performance concurrent queues, stacks and hasht tables to support safe and efficient data sharing.
Practical case:
1. Create a simple HTTP server
<?php use Swoole\HTTP\Server; $server = new Server('0.0.0.0', 9501); $server->on('request', function (Server\Request $request, Server\Response $response) { $response->end('Hello Swoole!'); }); $server->start();
2. Use protocol The process handles concurrent requests
<?php use Swoole\Coroutine; function processRequest(Server\Request $request, Server\Response $response) { // 模拟耗时操作 Coroutine::sleep(1); $response->end('Hello Swoole!'); } $server = new Server('0.0.0.0', 9501); $server->on('request', function (Server\Request $request, Server\Response $response) { Coroutine::create(function () use ($request, $response) { processRequest($request, $response); }); }); $server->start();
Advantages
Using the Swoole framework can bring the following advantages:
- High concurrency Processing capability: Can handle tens of thousands of concurrent connections at the same time, greatly improving the throughput of Web applications.
- Low resource consumption: Based on coroutine implementation, it avoids the resource overhead of thread switching and takes up less CPU and memory resources.
- Simplify code development: Provides a complete API to simplify the development of high-performance concurrent applications and improve development efficiency.
Summary
Swoole is ideal for PHP developers building high-performance web applications. Its coroutine concurrency, event-driven network and concurrent data structure features can significantly enhance application performance and throughput, effectively meeting the needs of high-concurrency scenarios.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
