Code shown as text output

Question

I'm a newbie to Facebook app development. It almost works when the page liked.php is shown (it's shown when a user liked the site), the PHP code is displayed as text output.

my liked.php code: deleted for privacy reasons ?>

Here's the output(it's shown as blank text):

I simply don't know why. Even the error_reporting(E_ALL); doesn't show anything. Simply blank text output. I use the newest facebook php sdk.

Answer 1

Sounds like you either don't have PHP installed or you're not using a file extension which invokes the PHP engine - is your file called [Blah].php?

Some things to check:

• You're serving the file from a web server (not locally)
• The server has PHP installed
• Your webserver is configured to use the PHP engine to handle the file type you're using (usually .php or .php4 or similar)
• creating a new file with just <?php phpinfo(); ?> and serving it should give you lots of info about your PHP install.
• If you have access to the server, you should be able to run PHP from the command line/shell

Answer 2

I guess the problem is not in the code but in the configuration of your server. You need to tell the server to execute the php code instead of displaying it.
