How to Retrieve the Request Payload in PHP for Asynchronous Calls?

Retrieving Request Payload in PHP

When working with asynchronous calls using technologies like ExtJS and AJAX stores, the request data may not be accessible through traditional methods like POST or GET. Instead, the data is transmitted in the "Request Payload" field, which is a JSON representation of the params.

PHP Solution

To retrieve this request payload in PHP:

1. Read Raw Request Body:

   • Utilize the file_get_contents('php://input') function to access the raw data from the request body.

2. Decode JSON Payload:

   • If the payload is in JSON format, decode it using $data = json_decode($request_body). This will convert the JSON data into a PHP array.

php://input Wrapper

php://input is a read-only stream that provides access to the raw request body. It is recommended for POST requests as it does not rely on special php.ini directives and is more efficient than other alternatives. It is not available for multipart/form-data requests.
