Autoloading Zend Framework 2 packages with the StandardAutoloader

问题

I was previously using a downloaded version of Zend Framework 2 and was basically able to do something like this:

// Set include paths (add Zend to the path)
set_include_path(get_include_path() . PATH_SEPARATOR . $__CONFIG['zendPath']);

// Setup the Zend Autoloader
require_once('library\Zend\Loader\StandardAutoloader.php');

$autoLoader = new StandardAutoloader(array(
    'namespaces' => array(
        'Zend' => $__CONFIG['zendPath'] . '/library/Zend'
    )
));

This works because all Zend packages are inside the library folder. I now wanted to use composer to load only the Zend packages I need. The problem I'm running into is that the packages get arranged in the following way:

zendframework/zend-cache/Zend/...
zendframework/zend-loader/Zend/...
zendframework/zend-validator/Zend/...
etc.

I tried having separate namespace declarations in the StandardAutoloader like this:

$autoLoader = new StandardAutoloader(array(
    'namespaces' => array(
        'Zend\Cache' => $__CONFIG['zendPath'] . '/library/zend-cache/Zend/Cache',
        'Zend\Loader' => $__CONFIG['zendPath'] . '/library/zend-loader/Zend/Loader',
        'Zend\Validator' => $__CONFIG['zendPath'] . '/library/zend-validator/Zend/Validator'
    )
));

That doesn't work. Am assuming the namespace probably can't have the backslashes in it? is there any way to make this work? Preferably without having to define each individual package.

回答1:

You just have to fix the paths:

$libs = $__CONFIG['zendPath'];
$autoLoader = new StandardAutoloader(array(
    'namespaces' => array(
        'Zend\Cache' => $libs . '/library/zend-cache/Zend',
        'Zend\Loader' => $libs . '/library/zend-loader/Zend',
        'Zend\Validator' => $libs . '/library/zend-validator/Zend',
    )
));

That should do the trick (it's un-tested, so I'm not sure about the trailing Zend

回答2:

Let it autoload Zend for you:

$autoLoader = new StandardAutoloader(array(
    'autoregister_zf' => true, // Auto load Zend Namespace..
    'namespaces' => array(
         // extra namespaces
    )
));
