Say there's a Symfony form that requires either one field to be submitted or another field. In this case, it's okay if both are submitted, but at least one is required. I had this exact situation come up earlier this week and all the solutions I found were related to adding validation to models.

What Dependencies Should be Injected into a Controller?
This article ist mostly about Symfony, but the advice here applies across frameworks. It's easier to define what's shouldn't be injected as a dependency: things global to the framework or the application being built. A form system is something global to the framework/application. Should the FormFactory be injected into every controller? How about templating? Should… Continue reading What Dependencies Should be Injected into a Controller?
Useful Health Check Endpoints in PHP Applications

Making Multiple Instances Play Nice with Symfony’s Autowiring
Symfony's autowiring is one of the best things to come to the framework in the 3.X series. Without it we would all still be extending ContainerAware base classes and be using a service locator. But what if we need multiple instances of somethign in the container?
