How to systematically learn PHP by yourself? To learn php, you first need to persist in learning and practice. At the same time, you must pay attention to theoretical knowledge and practical application. Through continuous learning and practice, you can gradually master the core skills of PHP development.
Here are the steps for a systematic self-learning PHP:
Learn basic programming concepts and syntax: Before learning PHP by yourself, you need to understand basic programming concepts and syntax, including variables, data types, control flow, functions, object-oriented programming, and more. You can choose an entry-level programming textbook to learn, such as "Head First PHP & MySQL" or "PHP & MySQL Video Tutorial".
Learn the basic syntax and features of PHP: Once you've mastered basic programming concepts and syntax, you can start learning PHP's features. This includes PHP's data types, variables, operators, conditional statements, loop statements, functions, arrays, and more. The official PHP documentation and online tutorials are good learning resources.
Learn how to use PHP to interact with databases: One of the most commonly used functions of PHP is to interact with databases. It is very important to learn how to connect to the database, query data, insert data, update data and delete data. MySQL is the most commonly used database in PHP development, and it is recommended to learn how to use MySQL and PHP integratedly.

Learn how to build dynamic web sites with PHP, including how to handle user input, generate dynamic pages, handle form submissions, create user login systems, and more. Learning some web development frameworks, such as Laravel and CodeIgniter, can make your web development more efficient.
Learn how to debug PHP code: Errors will inevitably occur when writing PHP code, and learning how to debug PHP code is very necessary. Using a debugging tool such as Xdebug can help you diagnose and fix errors.
Practice and Practice: Practice is the best way to improve your programming skills. By practicing PHP programming, you can help you consolidate the knowledge you have learned and understand how to apply them to solve real problems.
