🤔 What is PHP? #

👴 Who is the Father of PHP?

It was created by Rasmus Lerdorf in 1994 and is currently maintained by The PHP Group.

🎰 How PHP Works?

PHP code is executed on the server before the web page is sent to the client's browser, which allows for dynamic content generation based on user input, database queries, and other factors.

🤨 Where to Write PHP Code?

PHP code can be embedded directly into HTML code, making it a popular choice for web development.

📖 Is PHP Easy to Learn?

PHP is considered a relatively easy language to learn, especially for beginners who are new to programming. The syntax of PHP is similar to other C-style programming languages, and the language is designed to be easy to use and understand.

PHP also has a large and active community of developers who provide resources and support for beginners. There are many online tutorials, forums, and communities dedicated to helping people learn PHP, and the official PHP documentation is also comprehensive and easy to understand.

However, as with any programming language, the difficulty of learning PHP will depend on your prior programming experience and the complexity of the project you are working on.

💰 Is PHP a open-source?

Yes, PHP is an open-source language, which means that developers can use it freely and modify the source code to suit their needs.

📄 Hello World in PHP

Here's an example of a simple PHP program that prints Hello, World! to the console:

demo.php

Copied

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

When you run this program, it will display the message Hello, World! on the screen. The echo statement is used to output text to the browser.
