Editor’s Note: This is a guest post from Brian Muse, our lead developer on. He’ll be guiding you through a three part journey of PHP applications over the next few days. This tutorial is intended for readers who know the very basics of PHP and Object Oriented Programming (OOP) and would like to create a basic web application. To make this a little bit clearer, I’ve split this tutorial up into three separate posts. Each post will cover a major step in setting up a basic PHP web application. Series Overview We’ve got a lot of ground to cover.
Here’s a general outline about what to expect from each post in this series: Part 1 – Setting up the project and creating your first class • Creating an outline of the project • Setting up your files and folders • Creating a class to handle database operations: DB.class.php Part 2 – Building the rest of the backend • Creating a User class • Creating a UserTools class • Registration / Logging in / Logging out Part 3 – Building the front end • Forms • Form Handling • Displaying session data Setting up the Project Creating a Road Map It’s always a good idea to know where you’re going. Before you start creating and coding files it’s best to set your goals, map out the project and make decisions about your folder structure and what files you’ll need to make to accomplish your goal. The goal for this project is fairly simple: Create a basic PHP web application with user registration, the ability to log in and out and a way for users to update their settings. Files and Folder Structure An OOP PHP project utilizes classes and objects to perform many of the operations that the application requires. When planning, you should think about what classes you will need.

For this project we’ll be making three classes. The first is the User class, which will hold information about a particular user and a basic save() function. Another class, UserTools will contain functions that have to do with users, such as login(), logout(), etc.
The final class is the first class we’ll be coding: the database class. This class will handle connecting to the database, updating, inserting new rows, retrieving rows, and more. Aside from classes, we’ll utilize a file called global. Best Postscript Printer Driver there. inc.php. This file will be called on every page and will perform general operations that we commonly require. For example, it is this file that will handle connecting to the database on each page.

These include index.php, register.php, login.php, logout.php, settings.php and welcome.php. Driver For Usb To Parallel Printer Cable Windows 7. The final directory structure should look like the image below: Creating your database and users table You must have MySQL installed on your server to continue. You’ll first have to create a new database for your application. Within that database to create the users table we’ll be using for this tutorial, use the following SQL. ) ENGINE = MyISAM DEFAULT CHARSET = latin1; The “id” field is used as the primary key and will be the main unique identifier that we’ll use to differentiate between users in the database.
The “username” is also defined as a unique key. Other fields include “password” (which will be stored after it is hashed), “email”, and “join_date” (an sql datetime variable). Creating DB.class.php The first class we’ll be making for this project is one to handle database operations.
The goal is simple: to take the work out of using our database so that we deal with as little SQL as possible and to have data organized and returned in a easily readable format. Here is the code, with an explanation following. & gt; The Code Breakdown After the class definition you’ll see four variable declarations: $db_name, $db_user, $db_pass, and $db_host. These should be set accordingly, based on how you’ve set up your database.
