Drop PHP 5 support completely

[core23]

We started to drop all unsupported versions on the latest master branches. Maybe we could / should drop support for PHP 5 completely, because the active support ended yesterday. PHPUnit will drop PHP 5 support too with their next major release.

Maybe we should do the same. There is no release plan for the next major versions, so this might be the right way.

There is no release play for the next major releases

Don't talk while typing ^^

Maybe make a twitter poll for this? I feel this is kind of important.

PHP 5.6 still have security support. We must not drop it before it ends IMHO.

imho its too early to drop php 5.6 support

Hmmm… so the poll went surprisingly strongly in favor of dropping php 5. If we consider the twitter crowd is representative enough of our user base and we are ready to piss off 6% of it, we can safely drop php 5. What do we do? @OskarStark @rande @dbu ? Thoughts?

that is for the next major version? then i think its ok.

[core23]

Yes, for all next major releases. We have no release plan for these versions, so we have enough time to prepare the users.

This is deployed.
