ZF2: How to catch exceptions thrown by a view helper automatically - zend-framework2

Question

I have a some view helpers throwing exceptions on error. That's ok for development, but for production I would like to configure PhpRenderer to catch and log the exception without braking the hole view file to render - simply return nothing.
The PhpRenderer has the method:
public function __call($method, $argv)
{
if (!isset($this->__pluginCache[$method])) {
$this->__pluginCache[$method] = $this->plugin($method);
}
if (is_callable($this->__pluginCache[$method])) {
return call_user_func_array($this->__pluginCache[$method], $argv);
}
return $this->__pluginCache[$method];
}
Is it enough to overwrite this method?
How can I replace the PhpRenderer with my own?

Answer 1

You can do it by writing your own view strategy.
First, register your new strategy in the configuration.
return array(
'factories' => array(
'MyStrategy' => 'Application\ViewRenderer\StrategyFactory',
)
'view_manager' => array(
'strategies' => array(
'MyStrategy'
),
),
);
Then, create your own strategy
namespace Application\ViewRenderer;
use Zend\View\Strategy\PhpRendererStrategy;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\ServiceManager\FactoryInterface;
class StrategyFactory implements FactoryInterface
{
public function createService (ServiceLocatorInterface $serviceLocator)
{
$renderer = new Renderer ();
return new Strategy ($renderer);
}
}
and renderer.
namespace Application\ViewRenderer;
use Zend\View\Renderer\PhpRenderer;
class Renderer extends PhpRenderer
{
public function render($nameOrModel, $values = null) {
// this is just an example
// the actual implementation will be very much like in PhpRenderer
return 'x';
}
}
