Run php via command line using php filename.php in Terminal. 2. Use a local server like XAMPP by placing the file in htdocs and accessing it via http://localhost/filename.php. 3. Utilize PHP’s built-in server with php -S localhost:8000 and visit http://localhost:8000/filename.php. 4. Ensure proper file permissions (chmod 644) and server configuration for PHP handling.

if you are trying to execute a PHP file on your server, you need to use the PHP interpreter correctly. Here are the steps to run a .php file:

1. Run PHP File via Command Line
Using the command line is one of the most direct ways to execute a PHP file. This method bypasses the web server and runs the script using the PHP interpreter directly.
- Open Terminal on your system
- Navigate to the Directory containing your PHP file using cd /path/to/your/file
- Type php filename.php and press Enter
2. Execute PHP Through a Local Development Server
This method simulates a real web server environment. It’s useful when your PHP script interacts with HTTP requests, sessions, or forms.

- Ensure your PHP development server is installed (e.g., XAMPP, MAMP, or built-in PHP server)
- Place your .php file in the server’s document root (e.g., htdocs for XAMPP)
- Start the server service
- Open a browser and navigate to http://localhost/filename.php
3. Use Built-in PHP Development Server
The built-in server is lightweight and ideal for testing purposes. It does not require a full server stack installation.
- In Terminal, go to the folder where your PHP file is located
- Run the command php -S localhost:8000
- Open a browser and visit http://localhost:8000/filename.php
4. Configure File Permissions and MIME Type (if needed)
Sometimes the server may not recognize or execute the PHP file due to incorrect permissions or misconfigured handlers.
- Ensure the file has read permissions: chmod 644 filename.php
- Verify that your server is configured to parse .php files through the PHP module
- Check your server’s configuration file (e.g., httpd.conf or php.ini) includes the correct handler for .php extensions
