统一ZF2 Translator和AngularJS本地化

I built an application that uses ZF2 for authentification, routing, error pages etc., but the core functionalities on each view are implemented in AngularJS. The whole thing is localized, but in 2 seperate instances:

We have the ZF2 Translator, configured in module.config.php

'translator' => array(
    'locale' => 'de_DE',
    'translation_file_patterns' => array(
        array(
            'type'     => 'phparray',
            'base_dir' => __DIR__ . '/../language',
            'pattern'  => '%s.php',
        ),
    ),
),

containing key=>value pairs like 'app.frontend.title' => 'Title'.

And the Angular-Translate module, configured by

$translateProvider.useStaticFilesLoader({
    prefix: '/lang/',
    suffix: '.json'
});

containing a nested JSON object like {'app': {'buttons': {'send': 'Send now'}}}'

The PHP part contains some headlines, content for <title>, navigation,... pretty much everything that is displayed outside of my AngularJS apps. The Angular-JSON contains l10n for a lot of buttons, dialogs etc.

Is there a possibility to unify these two? Doesn't matter if I access the AngularJS json file from the php script or the other way round (get the .json dynamically served by PHP for Angular). But I can't figure out how to read JSON for the ZF2 Translator.

Why would have you have some translations handled by PHP and some others by Angular JS? Couldn't you get rid of the ZF2 Translator?
