Although I know that Oauth2::getMyopenid() is a method to obtain the user's openid, I would like to ask if getMyopenid() is a fixed usage?
Also, is the "::" double colon a fixed way of writing or does it have other meanings? Want to know what is happening and why. Thank you for your trouble.

getMyopenid() is a method name, a method name in the Oauth2 class. You can understand it as a fixed usage. It can be processed according to the different parameters you pass in and return to you the corresponding openid
The double colon means that this is a static method and needs to be used like this. If it is not static, use -> the arrow points to it
The scope resolution operator (also known as Paamayim Nekudotayim) or more simply a pair of colons can be used to access static members, class constants, and can also be used to override properties and methods in a class.
Nothing is better than the official explanation

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AMThe reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

Best PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PMPHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
