mod rewrite - PHP Mod_rewrite

Solution:

If you want

• http://website.com/profile.php?user=andy ->301->http://website.com/user/andy
• http://website.com/user/andy meanshttp://website.com/profile.php?user=andy

They are 2 different things, you'll need 2 rules:

RewriteEngine On

RewriteCond %{QUERY_STRING} ^user=([A-Za-z0-9]+)
RewriteRule ^profile.php /user/%1? [R=301,L]

RewriteRule ^user/([A-Za-z0-9]+)/?$ profile.php?a=b&user=$1 [L]
Copy code

The first will 301 (moved permanently) redirect to the pretty url. The second will allow your application to understand the pretty url.

Whenever you change the url scheme for a site you should take care of existing links. As such, that first rule is required/a good idea. You should not, however, need the first rule when using your own application. If your own application is generating links to profile.php?user=me - change your application code.

Solution:

You have to change your URLs when outputting them in your HTML to be in the format you want (/user/andy).

mod_rewrite will rewrite /user/andy to main.php?... not the other way around.

Solution:

What do you mean by my result?

mod_rewrite won't change existing links in your source code. Navigate towebsite.com/user/andy and you should see it work.
