You could create a form that posts to itself:

   echo "<form action=$PHP_SELF>" ;

Or you could generate a URL in a list that points to itself:

   echo "<a href='$PHP_SELF?cmd=view&id=12'>bob</a>" ;

This would set a variable called $cmd, with a value 'view' and a 
variable called $id, with a value 12, which you could use to view the 
details of the record with id 12.

The possibilities are endless.
