exec ( $statement ) echo "Success! \n " } catch ( \ PDOException $e ) We’ll start by creating a /src directory and a simple composer.json file in the top directory with just one dependency (for now): the DotEnv library which will allow us to keep our Okta authentication details in a.

The Client Credentials Flow is best suited for machine-to-machine communication where the client application is private (and can be trusted to hold a secret). There are different authentication flows in OAuth 2.0, depending on if the client application is public or private and if there is a user involved or the communication is machine-to-machine only. Okta is an API service that allows you to create, edit, and securely store user accounts and user account data, and connect them with one or more applications. We’ll make the API secure by using Okta as our authorization provider and implementing the Client Credentials Flow. In this article, I’ll show you how to build a simple REST API in PHP from scratch. You certainly don’t need a complex framework to build a simple but secure API though. They also make it easy to handle common issues like authentication/authorization, request validation, data transformation, pagination, filters, rate throttling, complex endpoints with sub-resources, and API documentation. They provide great tools to process requests and generate JSON responses with the correct HTTP status codes. Laravel/Lumen and Symfony’s API platform are the most often used examples in the PHP ecosystem. There are many great frameworks that can help you build REST APIs quickly. Most web applications these days are developed as single-page applications on the frontend, connected to backend APIs written in various languages. * The user object on which the operation was just performed.REST APIs are the backbone of modern web development. * The array of form values submitted by the user. * Redirect when a user has just logged in. For a module called custom_hooks_demo, the function will be as follows: /** user_login, node_insert, etc., Drupal calls any functions named according to the pattern of MODULE_HOOK with arguments to the function that have been specified by the module that introduces the hook. When an event occurs and it is identified by a string which is the hook, e.g. when a user logs in or out, a node is about to be saved, after it has been inserted in the database, updated, or deleted, etc. In other words, Drupal allows developers to interact with core code when some things happen in the system, e.g. The hook system which is as old as the project allows Drupal core to call certain functions defined in modules at specific places. The introduction of key Symfony components was meant to herald new beginnings and enforce a more professional programming paradigm. Drupal 8 is about Object-Oriented Programming (OOP) and a firm positioning of Drupal in the enterprise.
