You might know how to make different tab for fans and different for non fans but what is you want to redirect them after like your fan page to wall or any other fan page tab cause if you use php redirection code for fans area that will redirect user inside that tab.
To redirect users to wall after like fan page from welcome tab put the following code in fans area remember this is javascript code and will not work if javascript is disabled in user’s browser so you can put an alternative below this like a link to click. But dont worry mostly browsers have javaSCript automatically enabled now days. Put the following code in your fan area this will redirect them to any tab like wall.
[code lang=”js”]
<script type="text/javascript">
if (top != self) top.window.location = ‘http://www.facebook.com/SiteLocationPartnership?sk=wall’;
</script>[/code]
