My class autoload function is not working in my mvc - php

Question

MVC uploaded on cloud9, but when the auto-load class located in lib/init.php is not working. The .htaccess in the project folder or webroot folder files are not properly configured.
When I visit my project link https://my-mvc-hunteelar.c9users.io/ it gives this exception :
Failed to load class: Config' in /home/ubuntu/workspace/lib/init.php on line 21
I have 2 .htaccess files. The first .htaccess code in the main project folder is:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ webroot/ [L]
RewriteRule (.*) webroot/$1 [L]
</IfModule>
The second .htaccess file located in the webroot folder which is supposed to be the public folder of my MVC:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php [PT,L]
</IfModule>
The init.php code which contains the __autoload function.
require_once (ROOT.DS.'config'.DS.'config.php');
function __autoload($class_name){
$lib_path = ROOT.DS.'lib'.DS.strtolower($class_name).'class.php';
$controllers_path = ROOT.DS.'controllers'.DS.str_replace('controller', '', strtolower($class_name)).'class.php';
$models_path = ROOT.DS.'models'.DS.strtolower($class_name).'class.php';
if(file_exists($lib_path)){
require ($lib_path);
}
elseif (file_exists($controllers_path)){
require_once ($controllers_path);
}
elseif (file_exists($models_path)){
require_once ($models_path);
}
else{
throw new Exception('Failed to load class : '.$class_name);
}
}
Here is my code uploaded on cloud9 https://ide.c9.io/hunteelar/my-mvc

I think you already solved this. But the problem is with the initialization of your code.
$controllers_path = ROOT.DS.'controllers'.DS.str_replace('controller', '', strtolower($class_name)).'class.php';
should actually be:
$controllers_path = ROOT.DS.'controllers'.DS.str_replace('controller', '', strtolower($class_name)).'.controller.php';
Also
$models_path = ROOT.DS.'models'.DS.strtolower($class_name).'class.php';
Should be
$model_path = ROOT.DS.'models'.DS.strtolower($class_name).'.php';
In case it may help someone else.
