php获取post参数的几种方式

1、$_POST['paramName'] 只能接收Content-Type: application/x-www-form-urlencoded提交的数据

2、file_get_contents("php://input") 适用大多数类型的Content-type

php://input 允许读取 POST 的原始数据。和 $HTTP_RAW_POST_DATA 比起来，它给内存带来的压力较小，并且不需要任何特殊的 php.ini 设置。php://input 不能用于 enctype="multipart/form-data"。

3、$GLOBALS['HTTP_RAW_POST_DATA']; 总是产生 $HTTP_RAW_POST_DATA 变量包含有原始的 POST 数据。此变量仅在碰到未识别 MIME 类型的数据时产生。$HTTP_RAW_POST_DATA 对于 enctype="multipart/form-data" 表单数据不可用。

如果post过来的数据不是PHP能够识别的，你可以用 $GLOBALS['HTTP_RAW_POST_DATA']来接收，比如 text/xml 或者 soap 等等。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
