Php custom autoload

<?php
//custom autoload without composer
$to_map = [
    'App\\' =>  'app/',
    'Core\\' => 'Core/',
];

foreach($to_map as $prefix => $base_dir)
{
    spl_autoload_register(function ($class) use ($prefix, $base_dir) {

        $base_dir = __DIR__ . "/{$base_dir}";

        $len = strlen($prefix);
        if (strncmp($prefix, $class, $len) !== 0)
        {
            return;
        }

        $relative_class = substr($class, $len);

        $file = $base_dir . str_replace('\\', '/', $relative_class) . '.php';

        if (file_exists($file))
        {
            require $file;
        }
    });
}

Autoload.php

The introduction of spl_autoload_register() gave programmers 
the ability to create an autoload chain, 
a series of functions that can be called to try and load a class or interface. 

For example:

<?php
function autoloadModel($className) {
    $filename = "models/" . $className . ".php";
    if (is_readable($filename)) {
        require $filename;
    }
}

function autoloadController($className) {
    $filename = "controllers/" . $className . ".php";
    if (is_readable($filename)) {
        require $filename;
    }
}

spl_autoload_register("autoloadModel");
spl_autoload_register("autoloadController");
