General PHP question about the elements in this loop.
I'm forgetting something basic, and I'm having trouble tracking down the specific answer.
In this beginning section of a loop:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
Why are the empty parentheses necessary? Is this where an argument would go?

If i remember correctly, In PHP, and most programming languages, functions require those parentheses as part of the syntax. Some functions take arguments, and others don't but those parentheses are what distinguish them as functions.
