"Hello, World!" Program in PHP

The "Hello, World!" program is a simple script that outputs "Hello, World!" to the screen. This is often the first program that beginners learn in a new programming language. Here's how it looks in PHP:

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

Explanation:

• <?php: This tag opens a PHP code block.
• echo "Hello, World!";: This line of code outputs the text "Hello, World!" to the screen. echo is a language construct used to display output in PHP.
• ?>: This tag closes the PHP code block.

To run this program:

• Create a file named hello.php and paste the above code into it.
• Place the file in your web server's root directory (e.g., htdocs in XAMPP for Windows).
• Open a browser and navigate to http://localhost/hello.php to see the output.
