php-rest-telbook

A simple telbook web-application, using REST backend written in php and simple js/jquery frontend.

How Does it Work?

1. Browser opens index.html (you may omit it from the URL)
2. index.html loads all client/js files and makes the app interactive.
3. When browser AJAX-es to URL (that doesn't physically exist as a file) .htaccess reroutes request to server/index.php.
4. index.php setups error handling and creates $db, $request and $response. Then calls router.php.
5. router.php matches the URL and HTTP method and executes piece of code. Sends JSON response.
6. Browser receives JSON and renders the data appropriately. Uses client-render.js.

Utilizes:

.htaccess (for URL rewriting at the server backend, mod_rewrite needed)

HTML/CSS (browser visualization)
AJAX/JSON (transport of data between server and browser)
JQuery.js Library: https://api.jquery.com/ (ver 3.0+)

PHP: http://php.net/manual/en/ (ver 7.0+)

MySQL database (with 3 tables: persons, telephones, teltypes)

Backend URLs:

* [GET] persons
* [GET, POST, DELETE] persons/{ID}
* [GET] persons/{ID}/telephones
* [GET] telephones
* [GET, POST, DELETE] telephones/{ID}
* [GET] teltypes

JSON entities:

* person: {id:1, fname:"Krali", lname:"Marko", address:"St. Petersburg 63"}
* teltype: {id:2, name:"Mobile"} 
* telephone: {id:5, person_id:1, teltype_id:2, number:"0893199422"}
* message: {type:"error", text:"An Error Ocurred!"}
* server-response: {code:200, messages:[], person/persons/telephones...}
