Magento-lts: composer.json PHP minimum Requirement => 7.x

[kkrieger85]

Replaces #412

Update PHP minimum requirements to 7.1. for at least 1.9.4.x branch

Question: Also use php min req to 7.x for 1.9.3.x? We could add https://github.com/Inchoo/Inchoo_PHP7 to composer.json requirements

there was a comment, that there are current LTS OperatingSystems shipping with a 5.x release, are they out of support now already?

Ubuntu 14.04 LTS is now EOL (as of April 2019). Ubuntu 16.04 LTS uses PHP 7.0.

Do we care about RHEL/CentOS? I don't think we should because do we really want to support PHP 5.4 until June 2024?

[kkrieger85]

From my point of view, there is no need to support PHP 5.x.

There's the Inchoo/PHP7 package which brings PHP7 Support to Magento Core from 1.9.2.2. upon

With Magento Core 1.9.4.x this package was included in Magento Core

Besides that: We can strongly recommend using PHP7 at least for performance reasons

[colinmollenhour]

My vote is for 7.0 to be the minimum since it isn't that old and is still supported by Ubuntu 16.04 LTS for two more years.

Debian 8 still uses 5.6 and will not be EOL for 11 more months, but there is an upgrade path to Debian 9 which uses 7.0.

Of course, for people using Docker (which I advocate should be everyone) which distro you run doesn't matter. The official docker images actually stopped supporting 7.0 already with 7.1 being the oldest getting updates.

then Iam fine with it, too.

Question: Also use php min req to 7.x for 1.9.3.x?

I'd leave 1.9.3x as it is ... just add official patches (?), all other changes should be 1.9.4.x only.
