I have the url such as example.com/page.php?username=test. I want to rewrite this url into something like: example.com/test only if test follows the following regual expression: /^[0-9a-zA-Z_-]{1,35}+$/, else 404 page.

Try this:

# output: example.com/test
rewrite ^/([A-Za-z0-9_]+)$ /page.php?username=$1;

UPDATE:

{1,35} This expression allow from 1 to 35 character

{20} That have to exactly 20 character

The + say minimum 1 character

The correct full rewrite rule:

# output: example.com/test
rewrite "^/([A-Za-z0-9_]{1,35})$" /page.php?username=$1;
