something wrong with php

[iim]

hi. i just started using xammp and have one problem. i had no errors on installation. php looks like working . i put my php file in /htdocs directory but when i try to open it on my browser i cant see anything that was written between <?php ?>. sorry for my english and probably stupid question. thank you for answers in advance

- Are you sure, you use <?php instead of <? at the beginning (short_open_tags issue)?
- Are you sure your file has the fileextension .php (MIME type issue / passed by php parser)
- Are you sure you request the file through the http protocol instead of the "Open by" or doubleclick fileoption (understanding php is a serverside programming language issue)

Please open your sourcecode view in your browser when you just get a white sceen from a php file. What do you see there?
