How would this RewriteRule look?

How would I rewrite:

character.php?name=Agame

to:

character/Agame

If you want to rewrite requests to /character/… internally to /character.php?name=…, try this:

RewriteEngine on
RewriteRule ^character/([^/]+)$ character.php?name=$1 [L]

But if you really want to redirect requests to /character.php?name=… to /character/…, try this:

RewriteEngine on
RewriteCond %{QUERY_STRING} ^([^&]*&+)*name=([^&]+)
RewriteRule ^character\.php$ /character/%2? [L,R]
