PHP 开发工程师 怎样才算高级的开发工程师 有什么学习路径么？或者学习路线 ，要回那些东西
能独立解决90%的问题
能帮队友解决多数问题
能事先防止一些问题
至于怎么学，先从学会独立学习，独立思考和提有价值的问题，别问这种“怎么学”的问题开始
你会发现sf这里很多回答问题的人（当然包括我）基本不问问题，因为对我们来说，一些问题能问出来就代表这个问题其实已经解决了。另外一些问题问出来没有价值，它们要么有非常明确的唯一解答（于是很容易搜索到或很容易验证），要么答案可以写一本书，根本不是问答这种形式能承载的。

推荐阅读《Modern PHP - New Features and Good Practices》一书，这是我的读书笔记。
另外，对PHP内核感兴趣的，推荐深入理解PHP内核
很同意@mcfog的看法，鉴于最近也在思考相关问题，把我找到的一些关于php学习的资料贴出来，有基础的代码规范，也有一些建议，希望看完这些能对你有点帮助。

php最佳实践
php之道
推荐你两个优秀的资料，帮你跻身PHP高级工程师之列
《PHP扩展开发及内核应用》
《深入理解PHP内核》
当你的职称是高级工程师的时候你就是了
还有踩这个功能我觉得是这个社区最艹蛋的功能没有之一。
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP 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.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn 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 vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AMPHP 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.
Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AMKey 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.
Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AMIn 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: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AMPHP 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 and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AMPHP 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.
Why Use PHP? Advantages and Benefits ExplainedApr 16, 2025 am 12:16 AMThe 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),
