    Create a more detailed report (optional). The file above will output your current PHP version number, but if you want more information, such as system info, build dates, available commands, API information, and more, you can use the phpinfo() command. Save the file as info.php.
     <?php phpinfo(); ?>

    Open the file in your web browser. Once the file has been uploaded to the server, you can use your browser to load the file. Navigate to the location of the file on your server. For example, if you placed it in the root directory of your domain, you would visit www.yourdomain.com/version.php.
    • To see the full readout, visit www.yourdomain.com/info.php.

    Open the Command Prompt or Terminal. If you have PHP installed locally, you can use the Command Prompt or Terminal to check the version. This also works if you use SSH to create a remote connection to your server via the command line.
    • Windows - Press Win+R and type cmd.
    • Mac - Open Terminal from the Utilities folder.
    • Linux - Open Terminal from the dash, or by pressing Ctrl+Alt+T.

    Enter the command to check the PHP version. The command is slightly different on Linux. When you run the command, the installed version of PHp will be displayed.

    • Linux - php --version

    Fix the version not appearing in Windows. A common problem for Windows users is PHP not being included in the system path, resulting in the message ‘php.exe’ is not recognized as an internal or external command, operable program or batch file.[2]
    • Find the location of your php.exe file. This is usually C:\php\php.exe, but you may have changed this during installation.
    • Type set PATH=%PATH%;C:\php\php.exe and press Enter. Change the actual location if yours is different.
    • Run php -v again. You should now be able to see the version number.
