PHP JSON Requests: `file_get_contents(\'php://input\')` or `$HTTP_RAW_POST_DATA`?
PHP: file_get_contents("php://input") vs. $HTTP_RAW_POST_DATA for JSON Requests
When handling JSON data in PHP, the question arises: which is the preferred method for accessing the request body? Two options commonly used are file_get_contents("php://input") and $HTTP_RAW_POST_DATA.
file_get_contents("php://input")
file_get_contents("php://input") allows direct access to the raw request body. Compared to $HTTP_RAW_POST_DATA, it offers the following advantages:
- Less Memory Intensive: It does not require the use of php.ini directives, making it a more efficient option.
- Not Affected by Special Form Data: Unlike $HTTP_RAW_POST_DATA, file_get_contents("php://input") is not impacted by enctype="multipart/form-data" settings.
$HTTP_RAW_POST_DATA
$HTTP_RAW_POST_DATA is deprecated in PHP 7.0.0 and above. It can still be used in earlier versions, but it is recommended to migrate to file_get_contents("php://input") for better performance and functionality.
Request Type for JSON Data
Regarding the request type to use when sending JSON data, the most appropriate option is POST. This is because HTTP POST requests are specifically designed to transmit data without requiring it to be exposed in the request URL.
Conclusion
For accessing the body of JSON requests in PHP, file_get_contents("php://input") emerges as the preferred method, offering advantages such as memory efficiency and greater compatibility. When sending JSON data, using the POST request type ensures secure and reliable transmission of information.
The above is the detailed content of PHP JSON Requests: `file_get_contents(\'php://input\')` or `$HTTP_RAW_POST_DATA`?. For more information, please follow other related articles on the PHP Chinese website!

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
