//A simple file to auto-load namespaced and non-namespaced classes in your project

//You'll only need to include this file in all your project files to use autoloaded classes

//simply change the $classes_root variable to point to the folder where your classes reside

//this autoloader expects your files end in .php, modify line 31 if your case is different

//this utility doesnt however stop you from decaring namespacs as declared in classes your are using (of course)!

\spl_autoload_register(function($class_name) {

$classes_root = __DIR__."/App"; //change to reflect your classes root folder, i normally just use App/

//see if we have a chache and the queried class file path is already inc cache

if (\function_exists('apcu_add')) {

if (\apcu_exists($class_name) && \file_exists(\apcu_fetch($class_name))) {
