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.

The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3.
