PHP Web Development Tutorial – Web Development Using PHP – Tutorial For Beginners

Published October 3, 2022 · Updated March 10, 2024

If you’re venturing into the world of web development, one of the most versatile and widely-used scripting languages you must familiarize yourself with is PHP. Not only does it power a significant portion of the web, it’s also incredibly beginner-friendly. In this tutorial, we’ll guide you through the essential steps to create a dynamic website—a photo gallery—using PHP, along with other fundamental tools like HTML, Bootstrap, and MySQL.

Step 1: Download and Install Visual Studio Code

Before diving into the coding part, you need an efficient code editor. Visual Studio Code (VS Code) is an excellent choice for developers of all skill levels. It’s free, open-source, and provides powerful features like syntax highlighting, IntelliSense (code completion), and debugging support.

To get started, download Visual Studio Code from the official Visual Studio Code website. Choose the version compatible with your operating system and follow the installation instructions provided. Once installed, open VS Code, and familiarize yourself with its interface and available extensions that might help with PHP development.

Step 2: Download and Install XAMPP

The next step involves setting up a local server environment where you can run your PHP scripts. XAMPP is a popular PHP development package that includes Apache, MySQL, and PHP, which are essential for developing and testing web applications on your local machine.

Head over to the XAMPP website and download the version that suits your operating system. The installation process is straightforward. Once XAMPP is installed, launch the control panel and start the Apache and MySQL modules. These services are crucial for running your PHP website and database.

Step 3: Create a Photo Gallery Website

Now that your tools are ready, it’s time to build your photo gallery website using PHP, HTML, and Bootstrap, and connect it to a database using MySQL.

Step 3.1: Structure Your Project

Create a new folder in your htdocs directory within the XAMPP installation path, and name it photo-gallery. In Visual Studio Code, open this folder as your project directory.

Step 3.2: Write HTML and Bootstrap Code

Within your project directory, create a new index.php file. This will serve as the main page of your photo gallery. Here’s a minimal template to get you started:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Photo Gallery</title>
    <!-- Include Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        <h1>Welcome to My Photo Gallery</h1>
        <!-- Gallery Content Goes Here -->
    </div>
    <!-- Include Bootstrap JS and jQuery -->
    <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.2/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>

Step 3.3: Set Up the Database

Use XAMPP’s built-in PHPMyAdmin to create a new database named photo_gallery_db. Inside this database, create a table that will store information about the photos.

Step 3.4: Connect to the Database with PHP

In your index.php, create a PHP block to handle the connection to your MySQL database. Make sure to replace your_username and your_password with your actual database credentials.

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "photo_gallery_db";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

Step 3.5: Display Photos from the Database

Now, you’ll need to write a PHP script to fetch photo entries from your database and display them on your website. This involves a SELECT query and a loop to iterate through the results. Remember to include proper error handling for production environments.

Step 3.6: Add Photo Upload Feature

Implement a form in your HTML to allow users to upload photos. Then, write a PHP script to handle the file upload process and store the photo details in your MySQL database.

Final Thoughts

By following these steps, you will have crafted a simple yet functional photo gallery website using PHP, HTML, Bootstrap, and MySQL. As you become more familiar with these technologies, you can enhance your site with additional features like user authentication, pagination, and even a responsive layout.

With your local web server and code editor at the ready, you’re well on your way to becoming a proficient PHP web developer. Dive in, experiment, and don’t hesitate to consult the extensive online community and resources available for PHP developers. Happy coding!
