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.

PHP Basics: Getting Started with Server-Side Programming

Arrays and functions are essential PHP concepts. They help you organize data and create reusable code. Let's master them.

## PHP Arrays

Arrays store multiple values in a single variable. PHP has indexed arrays (numeric keys) and associative arrays (string keys). Both are powerful and commonly used.

## Array Functions

PHP provides many built-in array functions - count, sort, array_push, array_pop, array_merge, and more. These make working with arrays easy and efficient.

## Creating Functions

Functions let you write code once and use it multiple times. They make your code cleaner, easier to test, and more maintainable.

## Function Parameters

Learn how to pass data to functions, use default parameters, and return values. Understanding parameters is key to writing good functions.

## Built-in PHP Functions

PHP has thousands of built-in functions for strings, dates, files, databases, and more. Knowing the most useful ones saves time and makes coding easier.

Master PHP arrays and functions. Learn indexed arrays, associative arrays, array functions, and how to create reusable functions in PHP.

PHP Arrays and Functions: Working with Data

Object-Oriented Programming (OOP) helps you write better, more organized code. PHP supports OOP features that make development easier and more maintainable.

## Classes and Objects

Classes are blueprints for objects. Objects are instances of classes. Understanding this relationship is fundamental to OOP.

## Properties and Methods

Properties store data, methods perform actions. Learn how to define them, use visibility modifiers (public, private, protected), and access them.

## Constructor and Destructor

Constructors initialize objects when created. Destructors clean up when objects are destroyed. These are special methods that run automatically.

## Inheritance

Inheritance lets you create new classes based on existing ones. Child classes inherit properties and methods from parent classes. This promotes code reuse.

## Encapsulation

Encapsulation means hiding internal details and exposing only what's necessary. Use private and protected to control access to properties and methods.

## Polymorphism

Polymorphism allows objects of different classes to be treated the same way. It's a powerful feature that makes code flexible and extensible.
