I'm currently using:
if (isset($get['when']) && !strtotime($get['when']) && strtotime($get['when']) < time())
But i would also like it to include a way to check if $get['when'] is empty(''). How do I do this in the best manner?

empty( $get['when'] ) will return true if $get['when'] is an empty string. See the manual's entry on empty for more info.

if (isset($get['when']) && !empty($_GET['when']) && !strtotime($get['when']) && strtotime($get['when']) < time())
Use the empty function straight after you check that $_GET['when'] is set.

1empty performs several checks, 1 being if the variable is set, and another being the variable length, there is no need for the isset, please see the manual – RobertPitt Apr 11 '11 at 16:53
