I am trying to remove a trailing - (dash) at the end of the string. Here is my code:

<?php

$str = 'SAVE $45! - Wed. Beach Co-ed 6s (Jul-Aug)';

echo ereg_replace('([^a-z0-9]+)','-',strtolower($str));

?>

produces this:

save-45-wed-beach-co-ed-6s-jul-aug-

How can I remove a specific trailing character only if its there, in this case the dash?

Thanks in advance.
