Getting Started with PHP: A Beginner’s Guide to Server-Side Scripting

PHP is one of the most widely used server-side scripting languages for web development. Powering millions of websites worldwide, PHP enables developers to create dynamic, data-driven web applications. Whether you’re building a simple website or a complex application, PHP remains a reliable and flexible choice. At Crest Infotech, we use PHP to build secure, scalable, and high-performance web solutions. This beginner’s guide introduces PHP and explains how to get started with server-side scripting.

1. What Is PHP?

PHP (Hypertext Preprocessor) is an open-source server-side scripting language designed specifically for web development. PHP code runs on the server and generates HTML that is sent to the user’s browser.

Why PHP Is Popular

• Easy to learn for beginners
• Works seamlessly with HTML
• Strong database support
• Large community and ecosystem
• Widely supported by hosting providers

2. How PHP Works

PHP scripts are executed on the server when a user requests a webpage. The server processes the PHP code, interacts with databases if needed, and returns the final output as HTML.

Basic Workflow

1. User requests a PHP page
2. Server executes PHP code
3. PHP interacts with the database
4. HTML output is sent to the browser

3. Setting Up a PHP Development Environment

To start coding in PHP, you need a local development setup.

Popular Options

• XAMPP
• WAMP
• MAMP
• LAMP (Linux servers)

These tools include Apache, PHP, and MySQL, making setup easy for beginners.

4. Your First PHP Script

A basic PHP script looks like this:

<?php
echo "Hello, World!";
?>

This simple script outputs text to the browser and demonstrates PHP’s syntax.
