Question

I am using url rewrite like this

RewriteRule ^help$ help.php

so if user come with domain.com/help it work
but if user call page like domain.com/help/ it send err 404 page not found
how can fix this that in 2 case it do same job

Answer 1

Try this rule:

RewriteRule ^help/?$ help`

Adding /? makes the trailing-slash to be optional. The pattern then starts to match help as well as help/

You can test this rule here
