Rewrite URL in PHP with mod_rewrite

Question

The web server is Apache. I want to rewrite URL so a user won't know the actual directory. For example: The original URL:

www.mydomainname.com/en/piecework/piecework.php?piecework_id=11

Expected URL:

piecework.mydomainname.com/en/11

How to achieve it with mod_rewrite?

Answer 1

You need to define a rewrite rule (should be similar to this):

RewriteRule ^/(.*)/en/piecework/(.*)piecework_id=([0-9]+)(.*) piecework.mydomainname.com/en/$3

and put it in a .htaccess file under the main folder of you site

Full description of Rewrite rules here: http://httpd.apache.org/docs/2.0/misc/rewriteguide.html

EDIT

Made a mistake in my rule, hopefully I corrected it.

Answer 2

I found a fairly well written crash course in doing so here:

You'll need to specify the rules in .htaccess (in your site root).

Answer 3

I would suggest the following rule:

RewriteCond %{HTTP_HOST} ^(?!www)([^.]+)\.mydomainname\.com$ [NC]
RewriteRule ^(w+)/(\d+)$ /$1/%1/%1.php?%1_id=$2 [L]
