I want to use mod_rewrite with PHP, parse the URL with this format:
http://www.domain.com/Path-to-index.php/Class_to_Load/Function_to_Execute/Arguments_as_array_to_the_function
The class to load will be included of the directory classes, with a strtolower then ucfirst, like:
http://www.domain.com/Path-to-index.php/SAMPLE will include classes/Sample.php and execute the function action_index, because no function was used.
Then, when this url is open: http://www.domain.com/Path-to-index.php/SAMPLE/Login/User, PHP should include classes/Sample.php and execute action_Login($args = Array(0 => "User"));.
Please I need to know how to do that.
Your index.php could look something like this:
// @todo: check if $_SERVER['PATH_INFO'] is set
$parts = explode('/', trim($_SERVER['PATH_INFO'], '/')); // get the part between `index.php` and `?`
// build class name & method name
// @todo: implement default values
$classname = ucfirst(strtolower(array_shift($parts)));
$methodname = "action_" . array_shift($parts);
// include controller class
// @todo: secure against LFI
include "classes/$classname.php"
// create a new controller
$controller = new $classname();
// call the action
// @todo: make sure enough parameters are given by using reflection or default values
call_user_func_array(Array($controller, $methodname), $parts);
Your .htaccess for removing index.php from the url:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
It's always interesting to roll your own framework to learn more about PHP, but if you are really coding something bigger, I highly recommend using a well-known and well-documented framework. There are a lot of good frameworks out there, which are well-tested and used in production before. Just take a look at all the @todo notices above. These are all issues, which are already handled by a framework and you don't need to care about these things.
