`file_get_contents(\'php://input\') vs. $HTTP_RAW_POST_DATA: Which is the Best Method for Accessing JSON Request Bodies in PHP?`

How to Access JSON Request Body: file_get_contents("php://input") vs. $HTTP_RAW_POST_DATA

When receiving JSON data from a client-side XMLHttpRequest, you have two options for accessing the request body in PHP: file_get_contents("php://input") and $HTTP_RAW_POST_DATA.

file_get_contents("php://input")

This method provides a more efficient and reliable way to access the raw request body. It allows you to read the body directly without any memory overhead, making it suitable for processing large JSON payloads.

$HTTP_RAW_POST_DATA

While $HTTP_RAW_POST_DATA can also be used to access the request body, it has some limitations:

• It requires the enable_post_data_reading configuration directive in php.ini to be enabled.
• It can be memory-intensive for large request bodies.

Which Method to Use?

Based on these considerations, file_get_contents("php://input") is generally the preferred method for accessing JSON request bodies in PHP. It is more efficient, memory-friendly, and does not require any special configuration.

HTTP Request Type for JSON Data

When sending JSON data from a client, you should use the POST request method. POST allows you to send arbitrary data, including JSON, in the request body.
