i have a rating system on my website. and i need to include the code: <?php echo rating_bar('S01E02',5); ?> on every page that i want to see the rating bar. the thing is i want to be able to edit every page on the db. so i also want it to load the S01E02 from the db because thats the id of the rating bar and needs to be different on every page. so how can i include the print function inside the echo?
