Getting Started with PHP: Creating a Hello World Program
PHP, or Hypertext Preprocessor, is a popular programming language that is often used for creating dynamic websites and web applications. In this tutorial, we will be creating a simple “Hello World” program in PHP to help you get started.
Step 1: Create a new text file and name it “hello.php”.
Step 2: Open the file in a text editor and type the following code:
<?php echo "Hello, World!"; ?>
Step 3: Save the file and upload it to a web server that has PHP installed.
Step 4: Open a web browser and enter the URL of the file (e.g., http://www.example.com/hello.php).
You should see the message “Hello, World!” displayed on the screen. Congratulations, you have just created your first PHP script!
The code above starts with the PHP opening tag
<?php and ends with the closing tag
?>. The code in between these tags is executed as PHP code. In this case, the code is using the echo function to output the text “Hello, World!” to the web browser.
This is a basic example of how to use PHP to create dynamic web pages. From here, you can explore more advanced features such as variables, loops, and functions to create more complex scripts.
Keep in mind that PHP must be installed on the server where the script is running for the script to execute correctly. If you don’t have access to a web server with PHP installed, you can also install a local server such as WAMP or XAMPP on your computer to test your PHP scripts.
I hope you find this tutorial helpful in getting started with PHP programming. Happy coding!”
