使用.htaccess重写重定向URL的规则

Question

I am using .htaccess to redirect URLs on my website to avoid having links like for example page1.php.

I have a subfolder engine/index.php on the root domain that i intend to use to process the redirected URL.

eg i want the link localhost/user to rewrite to localhost/engine/index.php?view=user NOTE:The links being used ie /user is not a file or folder existing on the domain

Use this:

RewriteEngine On

RewriteRule ^([a-z]+)$ engine/index.php?view=$1 [NC,L,QSA]

Put this in your .htaccess file directly in your www/ directory.
([az]+) will match a group of letters (also capitals since the NC flag is used), but if something else than a letter is behind localhost/ the url won't be rewritten. If there are only letters behind localhost , the url will rewritten to engine/index.php?view=$1

The L flag indicates that this is the last RewriteRule , and the QSA flag appends the old querystring to the new one. For example: localhost/user?var=val will redirect to localhost/engine/index.php?view=user&var=val .

But , if the user goes to localhost/user?view=somethingelse , it will be rewritten to localhost/engine/index.php?view=user&view=somethingelse which means that if you do $_GET['view'] in engine.php , it will return "somethingelse" . To get the first view parameter from the querystring ( user ), use this regex in PHP:

$view = preg_replace('/view=([^&]+).*/', '$1', $_SERVER['QUERY_STRING']); //now, $view contains 'user'
