very messy autoloader benchmark

gistfile1.php

require_once 'app/autoload.php';

$classes = array(
    'Acme\\FakeBundle',
    'Zend_Log',
    'Zend_Fake_class',
    'Symfony\\Component\\HttpFoundation\\Response',
    'Symfony\\Bundle\\DoctrineBundle',
    'Acme\\HelloBundle\\AcmeHelloBundle',
    'Doctrine\\Foo',
    'Doctrine\\Bar',
);

$start = microtime(true);
$limit = 10000;

for ($i = 0; $i < $limit; $i++) {
    foreach ($classes as $class) {
        class_exists($class.$i);
    }
}

$duration = microtime(true) - $start;
var_dump($duration);
