Course Introduction：Many programmers who have worked for many years still have a very basic understanding of databases. They are confused as soon as they go out for interviews. They don’t understand basic SQL statements, more complex SQL queries, and SQL statement optimization. They don’t even know how to use them. Redis improves system performance and can withstand tens of millions of concurrencies. This set of courses will help you thoroughly understand MySQL locks, execution plans, indexes, MVCC & Redis transactions, cache, breakdown, penetration, avalanche, warm-up, etc., and you can complete all database interviews in one set!

Course Introduction：Redis is the most widely used storage middleware in the field of Internet technology. The understanding and application practice of Redis have become essential skills for mid-to-senior back-end developers today. MySQL is the preferred relational database for most Internet companies. Therefore, programmers cannot only understand the addition, deletion, modification, and query of the database and some simple usage skills. They also need to be proficient in some principles of MySQL to better deal with the problems encountered in actual work.

Course Introduction：PHP is very suitable for rapid development of Web projects, and Web projects are inseparable from the support of databases. PDO is the access abstraction layer of the database, which can provide a unified access interface for all types of databases, making development simpler and operation safer. In particular, PDO preprocessing technology fundamentally eliminates SQL injection attacks. Therefore, this course focuses on the mainstream PDO preprocessing technology and gives you a complete introduction to this development technology.

Course Introduction：Source code and handouts can be obtained from Q group: 589912610; 1. Why do you need to learn object-oriented PHP? Object-oriented is an advanced content of programming, which is relatively difficult to understand, but there is not much syntax knowledge. Common various PHP frameworks are based on object-oriented: laravel, thinkphp, etc. Although object-oriented preparation work is relatively tedious in the early stage, the later application is extremely convenient. The various classes written by yourself can be flexibly used in various projects. Only by mastering object-oriented can we step into the mysterious door of programming, allowing us to have new ideas on more issues. 2. What can you do after learning object-oriented? Construct common functional classes: database operation class (to realize the addition, deletion, modification and query of data table information and database link), user verification class (to realize user login, user registration and logout),
