number_format() ... it's under Math commands in the manual I believe
so you'd do:
<?php echo(number_format($cartoon['art_width'] * 2.54,1)); ?> x
<?php echo(number_format($cartoon['art_height'] * 2.54,1)); ?> cm
This also puts a , for every thousand by the way. It has an option to feed
it a specific format string, but I never use that part of it, so you'll
have to check the manual for that if you need it, sorry.
