PHP (htaccess) rewrite with $_GET request - php

Question

I made an simple framework for my website development.
I am currently using the this URL pattern:
www.example.com?r=account/login
But I would like to change it to:
www.example.com/account/login
remove r= from the URL.
I have seen YII framework does this. But I couldn't find a way to do this.
Solution:
Add the code below to your .htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^([a-zA-Z0-9-/]+)$ index.php?r=$1
RewriteRule ^([a-zA-Z0-9-/]+)/$ index.php?r=$1
</IfModule>`

Answer 1

What you are looking for are SEO friendly URLs which are quite common to use & implement. This is the .htaccess from a basic WordPress install which achieves a similar goal:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Then in index.php you can test this by doing a variable dump of $_GET like so:
echo '<pre>';
print_r($_GET);
echo '</pre>';

I see you found a solution however you don't/shouldn't need two rewrite rules for the same thing just to add the /. You can use a ? to make it optional. I also recommend using [L] on the rewrites so that it stops when the rule is met.
This is more of what you were looking for.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /index.php?r=$1 [L]
</IfModule>
