If you're encountering an error message that says "php is not recognized as an internal or external command," don't panic. This error message is common among command line users who are trying to run PHP scripts on Windows machines. Fortunately, there are several possible solutions to this problem.
In this guide, we'll walk you through the troubleshooting steps you can take to fix the "php is not recognized" error message on your Windows system.
Check Your Environment Variables
The first thing you should check when encountering this error message is your environment variables. Environment variables are system variables that specify paths for locating executables and libraries.
To check your environment variables, follow these steps:
- Open the Start menu and search for "Environment Variables."
- Click on "Edit the system environment variables."
- Click on the "Environment Variables" button.
- Under "System Variables," look for the "Path" variable and click "Edit."
- Add the path to your PHP installation directory (e.g., C:\php) to the list of paths in the "Variable value" field.
- Click "OK" to save your changes.
Add PHP to Your System Path
If adding the path to your PHP installation directory to your environment variables doesn't work, you may need to add PHP to your system path manually.
To add PHP to your system path, follow these steps:
- Open the Start menu and search for "Environment Variables."
- Click on "Edit the system environment variables."
- Click on the "Environment Variables" button.
- Under "System Variables," look for the "Path" variable and click "Edit."
- Click "New" and type in the path to your PHP installation directory (e.g., C:\php).
- Click "OK" to save your changes.
Restart Your Command Prompt
Sometimes, simply restarting your command prompt can fix the "php is not recognized" error message. To do this, close your current command prompt and open a new one.
Reinstall PHP
If none of the above solutions work, you may need to reinstall PHP. Make sure you download the latest version of PHP from the official website and follow the installation instructions carefully.
