PHP is one of the most popular server-side programming languages. It powers millions of websites and is essential for web development. Let's start learning PHP.

What is PHP?

PHP (Hypertext Preprocessor) is a server-side scripting language designed for web development. It runs on the server, processes requests, and generates HTML that browsers can display.

Setting Up PHP

You need a web server with PHP installed. Use XAMPP, WAMP, or MAMP for local development. These include Apache, MySQL, and PHP - everything you need.

PHP Syntax

PHP code is embedded in HTML using <?php ?> tags. Variables start with $, and statements end with semicolons. It's similar to JavaScript but runs on the server.

Variables and Data Types

PHP has dynamic typing - you don't declare variable types. Learn about strings, integers, floats, arrays, and objects. Understanding data types is crucial.

Functions and Control Structures

Functions help you organize code. Control structures (if/else, loops) let you make decisions and repeat actions. These are fundamental programming concepts.

Working with Forms

PHP excels at processing form data. Learn how to handle GET and POST requests, validate input, and keep your applications secure.

Common Questions & Answers

How do I get started with PHP?

Install XAMPP/WAMP/MAMP for local development. Create a .php file, write <?php echo "Hello World"; ?>, save it in htdocs/www folder, and access via http://localhost/yourfile.php. PHP code runs on server before HTML is sent to browser.

Run Explain

<?php
echo "Hello, World!";
echo "<br>";
$name = "PHP Developer";
echo "Welcome, " . $name;
?>

<!DOCTYPE html>
<html>
<head>
    <title>My PHP Page</title>
</head>
<body>
    <h1><?php echo "Hello from PHP"; ?></h1>
    <p>Current time: <?php echo date('Y-m-d H:i:s'); ?></p>
</body>
</html>

How do I handle form data in PHP?

Use $_GET for URL parameters and $_POST for form submissions. Always validate and sanitize input. Use htmlspecialchars() to prevent XSS attacks. Check if form was submitted before processing.
