In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

Strict types in PHP are enabled by adding declare(strict_types=1); at the top of the file. 1) It forces type checking of function parameters and return values to prevent implicit type conversion. 2) Using strict types can improve the reliability and predictability of the code, reduce bugs, and improve maintainability and readability.

Composer is a dependency management tool for PHP. The core steps of using Composer include: 1) Declare dependencies in composer.json, such as "stripe/stripe-php":"^7.0"; 2) Run composerinstall to download and configure dependencies; 3) Manage versions and autoloads through composer.lock and autoload.php. Composer simplifies dependency management and improves project efficiency and maintainability.

The... (splat) operator in PHP is used to unpack function parameters and arrays, improving code simplicity and efficiency. 1) Function parameter unpacking: Pass the array element as a parameter to the function. 2) Array unpacking: Unpack an array into another array or as a function parameter.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
