Yeah, at least in the U.S. There was a "PHP 6", but everything went so
wrong that they decided to just pretend that the number 6 doesn't exist.

We've still got 5.x stable, but that's because there's a security bug
for PHP every 20 days and it takes 30 days to stabilize an ebuild.

Here's a status report:

  * We've got the "eselect php..." stuff sorted out already so you can
easily switch between 5.6 and 7.0 on-the-fly.

  * Most extensions have a version that works with php-7.0.

  * Some PECL extensions only work with certain versions of PHP, yet are
not slotted. This will probably cause some headaches, but it's
pretty late in the game and I don't have the time to overhaul the
way we do extensions at the last minute. We may have to tell people
that they can't switch between php-5 and php-7 with certain
extensions (there are around 8 that cause problems).

  * The PHP upgrade itself is pretty harmless. Check your logs for
deprecation warnings. If there aren't any, you can probably just
switch to 7.0 with eselect and have everything work. It's a lot
faster and a bit less stupid than previous versions.

In any case, to bring this back on-topic, dev-lang/php now has a webp
USE flag too, so +1 for making it global.

I still see php5 installed as stable everywhere .. so perhaps php7 still

I vaguely remember that this can be done automatically, through

v5 and v7 are mostly compatible, and the few big changes have had
deprecation warnings for years.

What happened to 6: you know how some elevators don't have a 13th floor?

You mean like requiring USE=webp (new) if the user has USE=vpx (old)?
Sounds like a good idea. It's been totally broken for months and nobody
has noticed, though, so I'll probably wait until the next revision.

Ok so this is really OCD I know .. but might be worth adding the libs, e.g.

Enable webp support for GD in php-5.x via libvpx
Enable webp support for GD in php-7.x via libwebp
[[not checked for syntax]]

for example, but what do I know ... [ie. links the flag to the lib]

Half and half. The "suppoprt" is obviously a typo, but unfortunately,
PHP uses a bundled copy of GD, so that isn't.

...and there's more. In php-7.x, they've dropped libvpx in favor of
libwebp. Our existing USE=vpx (to pull in libvpx) therefore does nothing
in php-7.x, so I'm going to change it to USE=webp and have it pull in
libwebp instead. It takes forever to compile-test, but I'll push a fix
afterwards. Thanks for noticing!

No, libvpx is what's used to produce webp/webm things, afaict. So in the
case of php, that flag should probably be renamed.
