Evert Pot:
PSR-7 is imminent, and here's my issues with it.
Mar 04, 2015 @ 09:26:37

Evert Pot has written up a new post today with some of his thoughts about what's wrong with the PSR-7 proposal in the PHP-FIG. PSR-7 relates to a standardized interface for HTTP request and response handling.

PSR-7 is pretty close to completion. PSR-7 is a new 'PHP standard recommendation', put out by the PHP-FIG group, of which I'm a member of. [...] PSR-7 gets a lot of things right, and is very close to nailing the abstract data model behind HTTP, better than many other implementations in many programming languages.

But it's not perfect. I've been pretty vocal about a few issues I have with the approach. Most of this has fallen on deaf ears. I accept that I might be a minority in feeling these are problems, but I feel compelled to share my issues here anyway. Perhaps as a last attempt to sollicit change, or maybe just to get it off my chest.

He breaks up his thoughts into a few different categories, each with a summary and sometimes some code to help make his point a bit more clear. He talks about immutability, how objects will be immutable and shows an example of change in how Silex would have to function to follow the standard (with before/after). He then goes on to talk about the "issue with streams" and how the current proposal could allow for changing of the incoming request into a new one with new headers...not immutable. He ends the post talking about PSR-7's stance on buffering responses and how, even if his project doesn't adopt the PSR in the strictest sense, they may still take some inspiration from it.
