And the reason for this is that those parts are handled by web servers and php doesn't need to handle them. Isolation decision that simplifies things significantly infrastructure wise and that allowed for shared hosting to exist - which in turn brought the costs down and made web as popular and massive as it is today.
BTW, this architecture is not that different from what node and others are doing. Instead of having a language/framework that acts as a web server (but too simple, so you still need nginx in front), and then you need a queue service to delegate the jobs, you have a web server that delegates the jobs (requests) to isolated php processes. Model is the same and that's the model that's used everywhere today, just that the moving parts are partitioned a bit differently in different languages.
Of course, it's not a perfect solution to every problem, but works very good for any not-real-time web site/app and in the end RoR, Django, Symfony, etc. they all work in a very similar way (minus the syntactical nuances). For a massive traffic or language level high parallelism just use something else, no one argues against that.
