共存spl_autoload_register和composer autoload

Question

I got a legacy app which use spl_autload in order to load classes (they have no namespace)

<?php

spl_autoload_extensions('.class.php,.php');

set_include_path(
    $listOfDir
);

spl_autoload_register();

// require composer autoloader
// can't place that line before the call spl_autoload_register without breaking everything.
require __DIR__ . "/../vendor/autoload.php";

We recently introduced composer and Symfony container , dependency-injection and config component.

What I try to achieve is to have camelcase class loaded via composer (all new classes use camel cases to identify new vs legacy code) without causing BC breaks.

Do you have clues on how to get this working ? Do new classes must have a namespace ?

PS: New classes will spread accross "tons" of folders. The project size is 700k LOC.

Answer 1

So What I did is to put new class inside a src/ folder, add a namespace and add PSR-4 inside composer.json.

Because spl_autoload does not work with camelcase classes, i'm fine with that. :-)

"autoload": {
    "psr-4": {
        "MyNamespace\\NotLegacy\\": "src/"
    }
}
