The difference between require and include in PHP

Same points:

　1 , are both used to include files

2. include_once and require_once both check whether the file is included

Differences:

1. When require includes a file, if there is an error in the file , the program will interrupt and display a fatal error.

2. When including a file, if there is an error in the file, the program will issue a warning and continue execution.

3. require is generally used at the beginning of the program

4. include is generally used in the program flow

## In short:

require will report an error. If you put

at the beginning, you will get a warning. If you put

in the middle, you will only need_once.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
