How to code in PHP

To code in PHP, you’ll need a text editor or an integrated development environment (IDE) that supports PHP syntax highlighting and code completion. You’ll also need a web server installed on your computer or a web hosting service that supports PHP.

Here are the basic steps for coding in PHP:

  1. Open a text editor or IDE and create a new PHP file. You can give your file any name you like, but it must have a .php file extension.

  2. Start your PHP code with the <?php opening tag and end it with the ?> closing tag. All PHP code must be written between these two tags.

  3. Write your PHP code. PHP code can include variables, functions, loops, conditional statements, and other programming constructs. Here’s an example of a simple PHP program that prints “Hello, World!” to the screen:

    	echo "Hello, World!";

  4. Save your PHP file.

  5. If you’re running a local web server on your computer, place your PHP file in the root directory of your web server (such as htdocs for XAMPP or www for WAMP).

  6. Open your web browser and navigate to your PHP file using the web server’s URL. For example, if your PHP file is named hello.php and is located in the htdocs directory of XAMPP, you would navigate to http://localhost/hello.php.

  7. Your PHP code should be executed and the output should be displayed in your web browser.

  8. Note: If you don’t have a web server installed on your computer, you can use an online PHP sandbox like to test your PHP code. Simply copy and paste your code into the online editor, and click the “Run” button to execute it. The output will be displayed in the console.
