displays code instead of expected output

[alexrich]

When I try to test my setup by making the file test.php with the single line

<?php phpinfo(); ?>

then goto http://localhost/test.php it displays

<?php phpinfo(); ?>

instead of all the info.

Unfortunately my localhost/test.php only displays a 404 :p

Ok well have you installed PHP correctly? What Web server are you using? Is PHP enabled in the server? Did you restart the server? Did you set up the .php extension to be parsed by the PHP engine?
