.htaccess - Url rewrite and trim url -

i need precious help.

i have url:

http://domain.com/v/12345 

my ht access set pass 12345 php script like:

htaccess:

rewriterule  ^v/([a-za-z0-9_-]+)$  /script.php?v=$1 [l] 

script php:

http://domain.com/script.php?code=12345 

and works perfectly but.. , there but, write url so:

http://domain.com/12345/my-dog-is-very-fat 

can change htaccess works so? because if use /my-dog-is-fat or / 404 error.

i try explain better:

i share link seo keywords in url, example

mydomain.com/alphanumericcode/thi-is-my-dog-article 

where alphanumericcode of myscript.php?v=

this htaccess:

rewriteengine on rewriterule ^view/([a-za-z0-9_-]+)$ /view.php?v=$1 rewriterule ^folder/([a-za-z0-9_-]+)$ /filefolderlist.php?f=$1 rewriterule  ^home$            /index.php [l] rewriterule  ^report$          /report.php [l] rewriterule  ^play/([a-za-z0-9_-]+)$               /play.php?v=$1 [l]  ###added anubhava rewriterule ^v/([\w-]+)/?$ /script.php?v=$1 [l,qsa] rewriterule ^([0-9a-z]+)/.+$ /script.php?v=$1 [l,qsa,nc] ##end  rewriterule  ^privacy-policy$          /privacy.php [l] errordocument 404 404.php  

you can have new rule new uri scheme:

rewriteengine on  rewriterule ^v/([\w-]+)/?$ /script.php?v=$1 [l,qsa]  rewriterule ^([0-9a-z]+)/.+$ /script.php?v=$1 [l,qsa,nc]
