Add "Start time" and "Last restart time" to phpinfo() for opcache

[mikhainin]

One more piece of verboseness from our repository. When we debug things, sometimes it's useful to know the time of the event.
This adds start/restart/forcerestart timestamps to phpinfo()

Could you please take a look if this might be useful for the community? Let me know if I need to change/add anything.

not against the idea personally, makes sense.

Looks reasonable to me, what do you think @TimWolla ?

[TimWolla]

Not my area of expertise, but the output format is good now, the patch looks reasonable to me and if it helps you, I don't see why this shouldn't be included.

[TimWolla]

@devnexen Agreed; added a review saying so. But this is not my area of expertise, consider this a “small” approval 😃

[devnexen]

LGTM but giving it a bit time in case someone wants to jump in.

Thank you! That info may be useful, so this is good for me. I'd combine the declaration and initialization of the zend_strings, though (there is no more need to separate declarations and statements).

[devnexen]

Merged, thank you !
