A database is a collection of interrelated data. We can efficiently retrieve, insert and delete data from the database and organize the data in the form of tables, views, schemas, etc. Today we will introduce how to create a MySQL database through PHP
Basic steps for creating a MySQL database with PHP:
(1) Establish a connection between the PHP script and the MySQL server
(2) If the connection is successful, write a SQL query to create the database and store it in a string variable
(3) Execute the query
(4) Close the database
Next, in the article, I will introduce the process of creating a database in PHP in detail
<?php header("Content-Type: text/html; charset=utf8"); $servername = "localhost"; $username = "username" $password = "password" //创建链接 $conn = new mysqli($servername,$username,$password); if($conn->connect_error){ die("连接失败" .$conn->connect_error); } //创建一个为newDemo的数据库 $sql = "CREATE DATABASE newDemo"; //mysqli_query() 函数用于执行某个针对数据库的查询。 if($conn->query($sql) === TRUE){ echo "数据库创建成功"; } else { echo "Error creating database: " . $conn->error; } //关闭数据库 $conn->close(); ?>

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
