Getting Started with Web Application using PHP & MySQL

PHP is a programming language used to create dynamic contents with the database. Basically, PHP is used to develop Web Applications. In this Tutorial, we’re going to Develop a very simple Web Application & we’ll add features in our application in next parts of the tutorial. Here’s the Table of Content for this Tutorial series.

Pre-Requisites
Setting Up Server
Creating Database
Setting Up Template
CRUD APIs
UI for CRUD Operations

This Tutorial is for beginners. So, for keeping the things simple we’ll not use any PHP Framework. We’ll use Object-Oriented PHP for creating our Web Application.

Download Source Code

We’re going to create an Application to manage Doctors, Nurses etc & I’m going to give our application a name “Medibed”.

If you’re interested in creating Web Services using PHP. Here’s my article on Web Services in PHP

Restful Web Services in PHP Example – PHP + MySQL with Source Code

This Tutorial is designed using Object Oriented PHP. So, you must have a basic knowledge of Object Oriented Concepts in PHP before following this series. Here’s a quick overview of all those OOP Concepts.

Learn Object Oriented Programming In Php

Now, Let’s start our Tutorial.

Pre-requisites

Before starting this Tutorial, you must have a basic knowledge of PHP, MySQL, HTML, CSS, & JQuery to customize your application. We’ll use MySQL for creating Database for our Application & an Admin Template for creating interactive User Interfaces.

There are many Free Templates Available, for this Tutorial, I’m going to use This Beautiful Admin Template by almasaeed.

Setting up Server

To work on your local system you need to have PHP & MySQL installed on your system. So, the first step is to have a server to run our application. I’m going to install XAMPP because It installs both PHP & MySQL for us.

Run your server, go to your “htdocs” Folder inside “XAMPP” Forder & create a new folder there as “medibed”

Creating Database

It’s time to create a database for our Web Application.

I’m going to use very simple Hospital Database with 4 Tables, “doctors”, “nurses”, “patients” & “admins”.

You can use the database of your Web or Mobile App for which you are developing your Application.

Here’s the Database I’m going to use with the name “hospital_db”

& here’s the SQL script for this database

Database Script

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET AUTOCOMMIT = 0;
START TRANSACTION;
SET time_zone = "+00:00";

COMMIT;

Save the Above SQL Script in a file as “hospital_db.sql”.

Go to http://localhost/phpmyadmin, create a database as “hospital_db” & import the SQL File in your Database.

Now our database is ready & the next step is to set up our Server & AdminLTE Template for our Application.

Setting Up Template

First, you need to download AdminLTE Template. So download or clone AdminLTE & Unzip AdminLTE folder.

You’ll see these files & folders.

For keeping our project clean you need to copy & paste only Two Folders “bower_components” & “dist” from here to the folder we have created earlier with the name “medibed”.

Let start by creating a Layout Page for our Application.

Now create a new file as “master.php” at the root folder of your Folder & paste this code.

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">

<!-- AdminLTE App -->
<script src="../dist/js/adminlte.min.js"></script>

</body>
</html>

This is our master/layout page. We’ll load the content of all other pages inside this master page.

Let’s test our master page.

Create a new Folder as “Doctor” at the root of our project & inside this folder create a new file with the name “index.php”

Now, your “medibed” folder should look like this.

Add the Code below Inside your “index.php”

<?php
  $content = '<h2>Your Main Content Here</h2>';
  include('../master.php');
?>

Now, open your browser & go to this URL => http://localhost/medibed/doctor

you’ll see this

Congrats, you have successfully completed the first step toward creating your Web Application.

In the Next part of this Tutorial, we’ll perform CRUD operations using this beautiful Template.

Comment If you have any question or find any difficulty. I’m here to solve your problem.
