How do I check to see if a value was posted from a form in PHP?

I'm new to PHP. I have a form with two drop down boxes. I need to check if the user has submitted the form by selecting one or both of the values so i can then use those values to query a database.

In ASP I would just check to see if the length of the request was greater than zero.
How do I do this in PHP?

assuming your dropdown has name="state", you would use:
if( isset($_POST['state']) && !empty($_POST['state']) )
