Getting Started with PHP
To start using PHP, you need a web server, such as Apache or Nginx, and PHP installed on your system. Once you have these set up, you can create a PHP file with a .php extension, and any PHP code within the file will be executed on the server-side.
A basic PHP script starts with the opening tag <?php and ends with the closing tag ?>. Here’s an example:
<?php
$message = "Hello, PHP!";
echo $message;
?>
The above code defines a variable $message
with the value “Hello, PHP!” and then prints IT using the echo
statement. When you open the PHP file in a web browser, IT will display the message “Hello, PHP!”.
