How to rewrite urls using htaccess?

Question

Using htaccess how to turn this type of URL:

http://www.mysite.com/page.php?slug=hello-world

into this type:

http://www.mysite.com/page/hello-world

And not just this one url but all urls in the 1st format to the 2nd format.

Answer 1

If the second one is the URL you want people to see, use this:

RewriteRule ^page/(.*)$ /page.php?slug=$1

If it's the other way around:

RewriteRule ^page\.php?slug=(.*)$ /page/$1

EDIT: Also, make sure you have the following in your .htaccess before ANY RewriteRules:

RewriteEngine On

Answer 2

You may want to refer to here and this

Here is my thought to your solution:

RewriteEngine on
RewriteCond %{QUERY_STRING} ^slug=[^/]+$ [NC] 
RewriteRule ^page\.php$ http://www.mysite.com/page/$1? [R=301,L]
