Genrating SEO friendly url using .htaccess and modrewrite

Posted on September 29, 2014 by Suresh Kamrushi in PHP

Here how you can create clean SEO friendly url:
Normal practice of using url:
1) http://sforsuresh.in/user.php?u=123
2) http://sforsuresh.in/user.php?u=123&cat=php
3) http://sforsuresh.in/page.php

You can just rewrite it like
1) http://sforsuresh.in/user/123
2) http://sforsuresh.in/user/123/php
3) http://sforsuresh.in/page

Let see how we can achieve this:
1) You need to enable “mod_rewrite” of apache as below:
For enabling “mod_rewrite” open file “httpd.conf” and remove “#” from beginning of the below line:
LoadModule rewrite_module modules/mod_rewrite.so

2) Htaccess file:
Create .htaccess file in your root directory, just open notepad and save the file with”.htaccess” (no name only extension) as UTF-8. If you already have one, no need to create it again. Put the below lines:

RewriteEngine On
RewriteRule ^user/([0-9]+) user.php?u=$1 [NC, L]
RewriteRule ^user/([0-9]+)/([0-9a-zA-Z]+) user.php?u=$1&cat=$2 [NC, L]
rewirteRule ^page  page.php

Let see what i have written:
RewriteEngine: To enable we need to enable rewrite engine on.
RewriteRule: The RewriteRule directive is the real rewriting of rules that need to be executed.
$1 and $2 : Are variable used to represent dynamic values which we are pass in url against id and category.First ([0-9]+) represent $1 and second ([0-9a-zA-Z]+) represent $2 (from left to right) and so on.
NC: Non case sensitive pattern match
L : Stop the rewriting process immediately and don’t apply any more rules after this.

Few more directive you can use it as below:
RewriteBase : Specifies the URL prefix to be used. If your project inside some folder say myproject than you can write like this:
RewriteBase /myproject/
RewriteCond : defines a rule condition.One or more RewriteCond can precede a RewriteRule directive.

You can get more information or try and test your own rules:
1) Apache.org
2) Bluehost.com
