Building RESTful Web Services with PHP 7

Update operation

There can be two types of update operations:

• Update some attributes of a particular record
• Replace that particular record completely with a new one

Only thing that change to perform these two operations: HTTP method.

With the Update operation, to update some of attributes of the resource use:

HTTP method: PATCH

While to replace the whole resource use:

HTTP method: PUT

The URI and the parameters will remain the same:

URI: /{resource}/{resource_id}

Parameters: There can be multiple parameters in a query string. Initially, people try to pass these parameters in the body but actually, the PATCH and PUT parameters are passed using a query string.

Result: This should update or replace the resource based on the HTTP method.
