Introduction: PHP is a popular server-side scripting language that is widely used in web development. To succeed in the PHP field, you need to master a series of skills and learning content. This article will introduce the basic skills needed to do PHP and the key points to learn.

1. Basic skills:

1. Programming basics: Before learning PHP, it is necessary to have a certain programming foundation. Learning basic programming concepts, logical thinking and algorithm design is crucial for PHP development.

2. HTML and CSS: In web development, HTML and CSS are used to build the structure and style of web pages. PHP is often used together with HTML and CSS, so it is important for PHP developers to be familiar with these two technologies.

3. Database: PHP is usually used to interact with databases, save and retrieve data. Familiar with SQL and basic database principles, such as table design, indexing, etc., are essential skills for doing PHP.

4. Linux/Unix operating system: Most PHP applications run on Linux/Unix operating system. Familiarity with the basic operations of the system and the command line environment will enable you to better develop and debug PHP.

5. Version control: Using version control tools (such as Git) for code management is a standard practice in the modern development process. Mastering the basic principles and usage of version control will help improve development efficiency and team collaboration.

2. Learning content:

1. PHP language basics: The first step in learning PHP is to master its basic grammar, variables, operators, conditional statements, loop statements and other knowledge. Deepen your understanding of language features by writing simple PHP programs.

2. PHP framework: Learning and using a popular PHP framework (such as Laravel, Symfony, etc.) will help speed up development and improve the maintainability and reusability of code. In-depth study of the framework's features, routing, template engines, ORM, etc. enables you to develop PHP more efficiently.

3. Database operations: Learn how to use PHP for database connections and operations, learn SQL language, and understand database operations such as addition, deletion, modification, and transaction processing.

4. Secure coding: Web applications often face security threats. Learn how to write secure PHP code and avoid common security vulnerabilities (such as SQL injection, cross-site scripting attacks, etc.).

5. Performance optimization: Learn how to optimize the performance of PHP applications, optimize the server, database, network transmission, etc., and improve the response speed and concurrency of the application.

6. Front-end technology: Understanding some front-end technologies (such as JavaScript, jQuery, etc.) will help you better cooperate with PHP to achieve more complex interactions and effects.

Conclusion: To do PHP, you need to master a series of basic skills, such as programming basics, HTML and CSS, database, Linux operating system, version control, etc. At the same time, learning the basics of PHP language, PHP framework, database operations, secure coding, performance optimization and other key contents will enable you to develop more skillfully and efficiently in the PHP field. Through continuous learning and practice, from basic to advanced to professional, you can become an excellent PHP developer.
