How can one properly handle and parse non-array data like JSON objects received in $HTTP_RAW_POST_DATA in PHP?

When receiving JSON objects in $HTTP_RAW_POST_DATA in PHP, you can properly handle and parse the data by using the json_decode() function to decode the JSON string into a PHP object or associative array. Make sure to check if the data is valid JSON before decoding it to avoid errors.

// Check if the data is valid JSON
if (json_decode($HTTP_RAW_POST_DATA) !== null) {
    // Decode the JSON data into a PHP object or associative array
    $jsonData = json_decode($HTTP_RAW_POST_DATA);
    
    // Access the data elements as needed
    $value = $jsonData->key;
}
