- It is widely used, powering around 70% of websites.
- PHP was released in 1995 and has evolved from "Personal Home Page" to "PHP: Hypertext Preprocessor."
Setting Up the Development Environment:
- Recommended tools:
  - XAMPP as a web server.
  - Visual Studio Code as a text editor.
- Installation instructions for XAMPP and VS Code are provided.
Basic PHP Syntax:
- PHP code is embedded within <?PHP ... ?> tags.
- The echo statement is used to output text to the browser.
- PHP can be mixed with HTML.
Variables and Data Types:
- Variables in PHP start with a $ sign and can hold different data types: strings, integers, floats, and booleans.
- Examples of declaring and using variables are provided.
Control Structures:
- If Statements: Used for conditional logic.
- Switch Statements: Efficiently handle multiple conditions.
- Loops: for loops and while loops are used for repetitive tasks.
Working with Forms:
- GET and POST Methods: Differences and use cases for collecting data from HTML forms.
- Data validation and sanitization are emphasized for security.
Arrays and Associative Arrays:
- Arrays store multiple values and can be accessed using indices.
- Associative arrays use key-value pairs for more descriptive data handling.
Database Interaction:
- Instructions on connecting to a MySQL database using the MySQLi extension.
- Creating tables and inserting data into the database.
- Retrieving data from the database and handling exceptions.
User Authentication:
- Password hashing for security using password_hash() and verifying passwords with password_verify().
- Creating a registration form that stores user credentials in a database.
Sessions and Cookies:
- Sessions are used to store user information across multiple pages.
- Cookies store user data in the browser for personalized experiences.

Methodology and Instructions:

Setting Up XAMPP and VS Code:
- Download XAMPP from apachefriends.org and install it.
- Download VS Code from code.visualstudio.com and install it.
Creating a PHP File:
- Create a new folder in the htdocs directory of XAMPP.
- Create an index.PHP file and write PHP code using the appropriate syntax.

Connecting to MySQL:

Use the following code to establish a connection:


$conn = mysqli_connect('localhost', 'root', '', 'database_name');
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

Creating a Registration Form:
- Use HTML to create a form with username and password fields.
- Use PHP to handle form submission, validate input, and insert data into the database.
Using Sessions:
- Start a session with session_start() and store user data in $_SESSION.
Using Cookies:
- Create cookies with setcookie() to store user preferences.
