Introduction to PHP: The Language Behind Dynamic Web Pages

What is PHP?

PHP (Hypertext Preprocessor) is a server-side scripting language designed for web development. It helps create dynamic and interactive web pages, unlike static HTML which cannot change content automatically.

PHP code is executed on the server, and the result is sent to the client's browser as plain HTML.

Why Use PHP?

Easy to Learn – Simple syntax, similar to C, Java, and Perl.

Open Source – Free to use and backed by a large community.

Cross-Platform – Works on Windows, Linux, macOS.

Fast Performance – Integrates well with databases like MySQL.

Powerful Integration – Works seamlessly with HTML, CSS, JavaScript.

What Can PHP Do?

1. Create, read, write, and delete files on the server
2. Collect form data from HTML forms
3. Send or receive cookies
4. Add, delete, or modify data in databases
5. Control user-access (login systems)
6. Encrypt data and secure websites

Basic PHP Syntax

PHP scripts are written inside special tags:

1. <?php starts the PHP code.
2. echo is used to output text.
3. Statements end with a semicolon ;.

Example: Display Current Date

Output: Today is 2025/06/28

Popular Uses of PHP

1. WordPress (built in PHP)
2. Facebook (early versions)
3. Content Management Systems (CMS)
4. eCommerce websites (Magento, WooCommerce)
