How to Get Started with PHP
Getting started with PHP is easy. All you need is a web server and a text editor. You can then start writing and testing PHP scripts. To get started, you can refer to online tutorials and resources such as W3Schools or the PHP manual.
Creating a PHP File
To create a PHP file, simply open a text editor and save the file with a .php extension. You can then write PHP code within the file, which will be executed on the server when the file is requested.

echo "Hello World!";
This script will display "Hello World!" in the browser when the file is requested from the server.

Here is an example of a variable in PHP:
$text = "Hello World!"; echo $text;
This script will display "Hello World!" in the browser, just like the previous example.
PHP is a powerful and flexible language for web development, and its ease of use, compatibility with various operating systems, and integration with databases make it a popular choice for web developers. Whether you are just starting out or are an experienced programmer, PHP is a language worth learning.
