I needed to adjust my autoloader to do nothing when PHP tried to load Composer\Autoload\ClassLoader.php
. So I changed my Autoloader from:
function my_autoload($className){
require __DIR__ . "\\$className.php";
}
to
function my_autoload($className){
$path = __DIR__ . "\\$className.php";
if (file_exists($path)) require $path;
}
