Question

I’m following the basic description of Symfony Standard Edition on how to set up a new application with Symfony 2.

The thing is, this and all other guides explains that I need to have a vendors directory, where I should place third part libraries, such as Doctrine, Swiftmailer and Symfony itself.

However, Zend Server PEAR already comes with almost all of those libraries. As you know, I can even update my Symfony and Doctrine versions with the pear update command.

The question is: how can I set up that basic application to effectively use my PEAR libraries and ignore the vendors directory?

This is my version of app/autoload.php:

use Symfony\Component\ClassLoader\UniversalClassLoader;
use Doctrine\Common\Annotations\AnnotationRegistry;

$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
    'Symfony'          => array(__DIR__.'/../vendor/symfony/src', __DIR__.'/../vendor/bundles'),
    'Sensio'           => __DIR__.'/../vendor/bundles',
    'JMS'              => __DIR__.'/../vendor/bundles',
    'Doctrine\\Common' => __DIR__.'/../vendor/doctrine-common/lib',
    'Doctrine\\DBAL'   => __DIR__.'/../vendor/doctrine-dbal/lib',
    'Doctrine'         => __DIR__.'/../vendor/doctrine/lib',
    'Monolog'          => __DIR__.'/../vendor/monolog/src',
    'Assetic'          => __DIR__.'/../vendor/assetic/src',
    'Metadata'         => __DIR__.'/../vendor/metadata/src',
));
$loader->registerPrefixes(array(
    'Twig_Extensions_' => __DIR__.'/../vendor/twig-extensions/lib',
    'Twig_'            => __DIR__.'/../vendor/twig/lib',
));

// intl
if (!function_exists('intl_get_error_code')) {
    require_once __DIR__.'/../vendor/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->registerPrefixFallbacks(array(__DIR__.'/../vendor/symfony/src/Symfony/Component/Locale/Resources/stubs'));
}

$loader->registerNamespaceFallbacks(array(
    __DIR__.'/../src',
));
$loader->register();

AnnotationRegistry::registerLoader(function($class) use ($loader) {
    $loader->loadClass($class);
    return class_exists($class, false);
});
AnnotationRegistry::registerFile(__DIR__.'/../vendor/doctrine/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php');

// Swiftmailer needs a special autoloader to allow
// the lazy loading of the init file (which is expensive)
require_once __DIR__.'/../vendor/swiftmailer/lib/classes/Swift.php';
Swift::registerAutoload(__DIR__.'/../vendor/swiftmailer/lib/swift_init.php');

It’s clear that the autoloader is being configured to load the libraries from the vendor directory. I wanna use the libraries that comes with the pear package, however. How would that be implemented?

Answer 1

Just edit app/autoload.php to point to your pear delivered packages. Be careful that you use the proper versions. Probably be safer to just use the packages delivered with Symfony and then add paths to any additional libraries.
