Closures im Zend Framework

[tami]

hi,

hi,

Ich finde noch: "Reduce your closure usage for factories

It’s common usage in ZF 2 to handle dependencies through the use of closures as factories in the getServiceConfig of your Module.php class. Instead, you’d better use explicit class factories, and set define the factories in the module.config.php file (in the service_manager key). This is slightly more efficient (because closures are instantiated, it’s faster to create a string than a closure), allow you to cache config file (closure are not cacheable), and remove the unreadeable Module.php with tons of closures."

und

"However, I prefer factories for mainly readability and maintainability. With factories you don't end up with some massive configuration file with tons of closures all over the place.

Sure, closures are great for rapid development but if you want your code to be readable and maintainable then I'd say stick with factories."

Und bei einer Suche in den Klassen des Zend-Framework finde ich:
