为毛获取不到$GLOBALS["HTTP_RAW_POST_DATA"]?
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];dump($postStr);$postStr2 = file_get_contents("php://input");dump($postStr2);
为毛第一种情况输出为null,第二个可以输出,却貌似不是我要的。
之前没用过第一种,所以不知道第一种输出的结果是什么样的,也是和$_POST一模一样的一维数组么?
回复讨论(解决方案)
$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。
也就是说基本上$GLOBALS['HTTP_RAW_POST_DATA'] 和 $_POST是一样的。
但是如果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
明白了

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
