How to run PHP programs ?

PHP (Hypertext Preprocessor) is a popular server-side scripting language primarily used for web development. It is designed to generate dynamic web pages and interact with databases. Running PHP programs involves setting up a development environment, whether locally or on a live server.

In this article, we'll discuss how to run PHP programs on your local machine and on a web server.

Setting Up the Environment to Run PHP

Step 1: Download the XAMPP

Go to the official website of XAMPP and install it - XAMPP.

Step 2: Start the XAMPP Program Control Panel.

Click on the "Start"  button next to the "Apache" to start your Apache Web Server. Also, start "MySQL" if your PHP programs depend on a MySQL database to run.

Step 3: Create the PHP File

• Place your PHP files in the "htdocs" folder located under the "XAMPP" folder on your drive.
• The initial path is "your_drive_letter:\xampp\htdocs" for your Web server.
• Make sure that your PHP files are saved as a ".php" file extension.

Now, create the file index.php inside the htdocs folder and write your below given PHP code in it.

Open your terminal and write the below code in the terminal to run the PHP program.

Conclusion

To run PHP programs, you need to set up a suitable environment, either locally or on a live web server. For local development, you can install server packages like XAMPP, WAMP, or MAMP, which provide PHP, Apache, and MySQL in one installation. Once set up, you can create PHP files with a .php extension and place them in the server's root directory (e.g., htdocs for XAMPP). After starting the server, you can access the PHP file in your browser using http://localhost/filename.php.
