Zend Framework 2 : Using Zend Framework 1 libraries

Do you still need some components of Zend Framework 1 in your Project that use Zend Framework 2 ? It easy to use Zend Framework 1 libraries in Zend Framework 2 by register Zend Framework 1 libraries in Zend Framework 2 StandardAutoloader or by register at composer’s ClassLoader.

1. By ZF2 StandardAutoloader

//we still need set include path because some component still use require_once others
set_include_path(implode(PATH_SEPARATOR, array($Zf1Path, get_include_path())));
Zend\Loader\AutoloaderFactory::factory(array(
    'Zend\Loader\StandardAutoloader' => array(
        'autoregister_zf' => true,
        'prefixes' => array(
          'Zend_'     => $Zf1Path.'/Zend'
        ),
    )
));

2. By Composer’s ClassLoader

$loader = include 'vendor/autoload.php';
//we still need set include path because some component still use require_once others
$loader->setUseIncludePath($Zf1Path);
$loader->add('Zend_', $Zf1Path.'/Zend');

If you’re working with Zend Framework’s Skeleton Application, you should change init_autoloader.php like the following :

$Zf1Path = '/path/to/your/zf1/library';

// Composer autoloading
if (file_exists('vendor/autoload.php')) {
    $loader = include 'vendor/autoload.php';
    $loader->setUseIncludePath($Zf1Path);
    $loader->add('Zend_', $Zf1Path.'/Zend');
}

$zf2Path = false;

if (getenv('ZF2_PATH')) {           // Support for ZF2_PATH environment variable or git submodule
    $zf2Path = getenv('ZF2_PATH');
} elseif (get_cfg_var('zf2_path')) { // Support for zf2_path directive value
    $zf2Path = get_cfg_var('zf2_path');
} elseif (is_dir('vendor/ZF2/library')) {
    $zf2Path = 'vendor/ZF2/library';
}

if ($zf2Path) {
    include $zf2Path . '/Zend/Loader/AutoloaderFactory.php';
    //we still need set include path because some component still use require_once others
    set_include_path(implode(PATH_SEPARATOR, array($Zf1Path, get_include_path())));
    Zend\Loader\AutoloaderFactory::factory(array(
        'Zend\Loader\StandardAutoloader' => array(
            'autoregister_zf' => true,
            'prefixes' => array(
                'Zend_'     => $Zf1Path.'/Zend'
            ),
        )
    ));
}

if (!class_exists('Zend\Loader\AutoloaderFactory')) {
    throw new RuntimeException('Unable to load ZF2. Run `php composer.phar install` or define a ZF2_PATH environment variable.');
}

How about calling, just take a look like the following :

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

class IndexController extends AbstractActionController
{
    public function indexAction()
    {
        $date = new \Zend_Date;
        print_r($date->toArray());
        
        return new ViewModel();
    }
}
