Try creating the file
/var/www/test.php with the following contents:
php code
<?php phpinfo(); ?>
Then on the same network, open a browser and go to
http://192.168.0.??/test.php
...but replace the IP with the local IP of your server.
If you run the browser
on your server you can go to
http://localhost/test.php.
If everything is working, you'll see a page listing all of PHP's settings and installed modules.
