php commands not working

[kakalahori]

hi
i installed wamp5 1.7.4in windows 7 and started wamp server
using komodo edit i created a file with a test command

<? php phpinfo(); ?>

but all i get is blank page

i tried html it would work fine but none of the command for php is working

i tried it even restarted the computer changed wampserver 2.2 to wamp5 1.7.4 and still nothing works

i event tried <? php echo"1234"; ?>
but nothing turned out to be visible its blank

previously i had a problem when my apache server was not running
port 80 was in use after an hour of struglle when i stopped skype it began to work

might these information would be helpful to you
