php - Regexp OR operator -


i'm using .htaccess generate nice looking links, , need include or on slash

so example domain.com/page/12/a/ , domain.com/page/12/a work

what i've tried:

rewriterule ^page/([^/]*)/([^/]*)(/?)([^/]*) index.php?do=atoz&category=$1&letter=$2&type=$3 [l]

in case simple quantifier ? zero or one should work.

^page/([^/]*)/([^/]*)(?:/([^/]*))?                       ##         #

edit: might non-matching group can quantify optional. starts ?:.
