Introduction to Core PHP Programming

PHP is one of the popular server-side programming languages used to develop dynamic websites and web applications. If you want to learn website development, creating a login system, building a dynamic news portal, or developing business management software, learning Core PHP is a useful starting point.

In this Core PHP tutorial for beginners, we will explain PHP from the basics, including its definition, uses, working process, installation, first program, and practical examples. No advanced programming knowledge is required to get started.

1. What Is PHP?

PHP stands for PHP: Hypertext Preprocessor. It is an open-source, general-purpose scripting language widely used for web development.

PHP runs on a web server and generates output that can be displayed in a browser. It can also interact with databases to store, retrieve, update, and delete information.

For example, when you log in to a website, PHP can verify your credentials, check user information in a database, and allow access to your account if the credentials are valid.

Simple PHP Program

Create a file named index.php and write the following code:

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

Output:

Hello World!

Explanation of the Code

• <?php starts a PHP code block.

• echo displays text or other output.

• "Hello World!" is the text displayed on the screen.

• ; marks the end of the statement.

• ?> closes the PHP code block. In files containing only PHP, the closing tag is commonly omitted.

This is one of the simplest examples for understanding PHP programming.

2. Why Do We Use PHP?

PHP is used to create dynamic and interactive websites. Unlike a simple static HTML page, a PHP-powered website can process user input, communicate with a database, and generate content based on changing information.

The following are some common uses of PHP:

1. User Login and Registration: PHP validates user information and manages authentication.

2. Contact Forms: PHP processes submitted information and can send emails.

3. News Portals: PHP retrieves news articles from a database and displays them on the website.

4. E-commerce Websites: PHP handles products, shopping carts, customer accounts, and order processing.

5. Admin Panels: Website administrators can add, edit, delete, and manage content.

6. School Management Systems: PHP can manage student records, fees, attendance, and examination data.

7. CRM Software: PHP can help manage customer information, leads, tasks, and business activities.

8. Inventory Management: PHP can manage products, stock quantities, suppliers, and transactions.

PHP is useful because it can be integrated with databases such as MySQL and MariaDB and works with HTML, CSS, and JavaScript.

3. Where Is PHP Used?

PHP is used in different types of websites and web applications.

Business Websites

Companies use PHP to develop dynamic websites with service pages, enquiry forms, admin panels, and content management features.

E-commerce Websites

PHP can power online shopping systems with product categories, shopping carts, customer accounts, and order management.

News Portals

News portal websites use PHP to publish articles, manage categories, upload images, and display the latest news from a database.

School Management Software

PHP can be used to develop systems for student registration, attendance, fee management, examinations, and reports.

Customer Relationship Management Software

PHP can power CRM applications that help businesses manage customer records, sales leads, quotations, tasks, and follow-ups.

Content Management Systems

WordPress is a well-known example of a content management system built primarily with PHP. It allows users to create and manage website content without manually coding every page.

4. How Does PHP Work?

To understand PHP, consider a simple login system.

The process generally follows these steps:

Step 1: User Opens a Website

The user opens a website in a browser and enters their email address and password.

Step 2: The Browser Sends a Request

The submitted information is sent to the web server through an HTTP request.

Step 3: PHP Processes the Request

PHP validates the submitted data and executes the required business logic.

Step 4: PHP Communicates With the Database

If required, PHP queries a database to retrieve the user's account information and verify the password securely.

Step 5: The Server Returns a Response

If authentication succeeds, the application can create a session and display the user's dashboard. Otherwise, it can display an appropriate error message.

This process allows PHP to create interactive websites that respond to user actions.

5. Difference Between Client-Side and Server-Side Scripting

Client-side and server-side scripting perform different roles in web development.

Real-World Example

Suppose a user fills out a registration form.

JavaScript can check whether the email field is empty before submitting the form. PHP must independently validate the submitted data on the server and can save valid information to the database.

Using both client-side and server-side validation helps create more reliable web applications.

6. How to Install PHP Using XAMPP

Beginners can use XAMPP to create a local PHP development environment on a Windows computer.

XAMPP includes Apache, PHP, and MariaDB, along with other useful components. It allows you to run PHP programs locally without purchasing web hosting.

Step 1: Download XAMPP

Visit the official Apache Friends website:

https://www.apachefriends.org/

Download the appropriate XAMPP version for your operating system and install it.

Step 2: Create a Project Folder

After installing XAMPP, open the following folder:

C:\xampp\htdocs\

Create a new folder named myproject.

Your project directory will be:

C:\xampp\htdocs\myproject\

This folder will contain your PHP files.

Step 3: Start Apache

Open the XAMPP Control Panel and click the Start button next to Apache.

For database-based projects, you can also start the MySQL/MariaDB service provided by your XAMPP installation.

Step 4: Create Your First PHP File

Inside the myproject folder, create a file named index.php.

Add the following code:

<?php
echo "Welcome to PHP Programming!";
?>

Save the file.

Step 5: Run the PHP Program

Open your web browser and visit:

http://localhost/myproject/index.php

You should see the following output:

Welcome to PHP Programming!

Important: Do not open the PHP file directly using a file:/// address. PHP must be executed through a PHP-enabled server, such as the local Apache server provided by XAMPP.

7. Your First Practical PHP Program

Let's create a slightly more detailed PHP program.

Create a file named index.php and add this code:

<?php
echo "Welcome to PHP Programming!";
echo "<br>";

echo "This is my first PHP program.";
echo "<br>";

echo "I am learning web development.";
?>

Output

Welcome to PHP Programming!

This is my first PHP program.

I am learning web development.

Explanation

• The first echo statement displays a welcome message.

• The HTML <br> tag creates a line break.

• The second echo statement displays another message.

• The final statement displays the third message.

This program demonstrates how PHP can generate HTML output for a browser.

8. Understanding Variables in PHP

A variable is used to store information that a program can use later.

In PHP, variable names begin with the dollar sign ($).

For example:

<?php
$name = "Parmanand";

echo "Welcome, " . $name . "!";
?>

Output:

Welcome, Parmanand!

Explanation

• $name is a variable.

• "Parmanand" is the value assigned to the variable.

• The assignment operator = assigns the value.

• The dot (.) joins strings together in PHP.

• echo displays the final message.

If you change the value of $name to "Rahul", the output becomes:

Welcome, Rahul!

Variables are important for building dynamic websites because they allow PHP to display different information for different users.

9. Real-World Example: Displaying a Dynamic Welcome Message

Imagine that you are developing a business website or customer dashboard.

Instead of writing a separate welcome message for every customer, you can store the customer's name in a variable and display it dynamically.

Example:

<?php
$customerName = "Rahul";

echo "<h1>Welcome, " . $customerName . "!</h1>";
echo "<p>Thank you for visiting our website.</p>";
?>

The browser displays a welcome heading and a thank-you message.

In a real application, the customer's name might be retrieved from a database after authentication.

For production websites, dynamic values should be properly escaped before being inserted into HTML. For example, htmlspecialchars() can help prevent HTML injection and cross-site scripting when used appropriately.

10. Real-World Example: PHP for a News Portal

Suppose you want to develop a dynamic news portal.

The administrator publishes a news article with the following information:

• News Title: New Road Inaugurated in Raipur

• Category: Chhattisgarh

• Publication Date: 9 October 2026

PHP can process the article information and store it in a database such as MySQL or MariaDB.

When a visitor opens the news portal, PHP can retrieve the published articles and display them on the homepage.

This approach offers several benefits:

• Administrators can publish new articles without manually creating separate HTML pages.

• News categories can be managed dynamically.

• Visitors can browse the latest articles.

• Published content can be updated through an admin panel.

• The same website template can display many different articles.

This is one example of how Core PHP can be used to develop a real-world web application.
