+# using PHP MVC REST API
+
+Representational state transfer (REST) is a software architectural that seperates models, views and controller component and interconnectes them. it is a client-server architecture.
+
+# Project Overview
+
+This project is created for getting simple knowledge of php with MVC framework.
+
+Project includes PHP as a backend language and MySql database.
+
+Project includes email Authentication and CRUD operation on different records.
+
+# Connection with MySql using PHP
+
+```php
+class Model {
+    protected $connection = "";
+    protected $servername="localhost";
+    protected $username="root";
+    protected $password=""; // your mysql database password
+    protected $dbname=""; // database name
+
+    // connecting with database
+    function __construct() {
+        mysqli_report(MYSQLI_REPORT_STRICT);
+        try {
+            $this->connection = new mysqli($this->servername, $this->username, $this->password, $this->dbname);
+        } catch(Exception $e) {
+            echo "Connection to database is failed".$e->getMessage();
+            exit;
+        }
+    }
+}
+```
+
+# Calling Model components from Controller
+
+```php
+require_once('Models/Model.php');
+session_start();
+
+class Controller extends Model {
+    function __construct() {
+            parent::__construct();
+            $baseDir = basename(__FILE__); 
+            $location = substr($_SERVER['PHP_SELF'], strpos($_SERVER['PHP_SELF'], $baseDir) + strlen($baseDir));
+            if($location) {
+                switch($location) {

+                }
+            }
