Get rid of autoload.php

Inspired from simple-psr-4-autoloader .

Have you ever used a composer.json file purely for the need of registering a PSR-4 autoloader? I have, and it always felt a little weird to require such a hunk of code for such a simple task. It adds a vendor folder and a bunch of empty files. I don’t like that overhead when it’s not necessary.

It’s also not ment to replace Composer in any way, because that is way more optimized. It’s just that for a simple plugin or theme you don’t need the overhead Composer creates.

<?php
spl_autoload_register(function (string $class_name): void {
    $namespace = 'MyProject';
    if (strpos($class_name, $namespace) === 0) {
        $class_file = './src';
        $class_file .=
            str_replace(
                [$namespace, '\\'],
                ['', DIRECTORY_SEPARATOR],
                $class_name)
                . '.php';
        if (file_exists($class_file)) {
            require_once $class_file;
            return;
        }
    }
});

Add this code to autoload.php and include it in index.php (or any other entrypoint you may have).
