.htaccess url友好的PHP

I want to turn a url in the url friendly. my url:

http://www.builtbydoctors.com/qrcode/index.php?id=93

and i want this url friendly:

http://www.builtbydoctors.com/qrcode/**title**/93

the title changes depending on the id.

my problem is in the htaccess file in the creation of the regular expression. there have:

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteRule ^index/([a-z0-9-]+)/([0-9]+)/?$ /index.php?id=$2&nome=$1 [NC]
</IfModule>

I know that the problem is in the htaccess file, can help me solve this problem in regular expression?

Your rule will work for url

http://www.builtbydoctors.com/index/title/93

If you want use it for your example then you should change your rule to

RewriteRule ^qrcode/([a-z0-9-]+)/([0-9]+)/?$ /index.php?id=$2&nome=$1 [NC]

Try to do so

<IfModule mod_rewrite.c>
    RewriteEngine On
    # Using this you can tell Rewrite to have a base url
    RewriteBase /qrcode
    RewriteRule ^([a-z0-9-]+)/([0-9]+)/?$ index.php?id=$2&nome=$1 [NC,L,QSA]
</IfModule>

Hope that works!
