Openapi-generator: PHP 5.x reaches the end of life by the end of 2018

[wing328]

Description

PHP 5.x reaches the end of life by the end of 2018 so we need to upgrade our PHP clients, servers to use PHP 7.x as the default.

Ref: http://php.net/supported-versions.php

openapi-generator version

I suggest we do it as part of the 4.0.0 release (next major release)

Suggest a fix/enhancement

If anyone wants to help on this, please reply to let us know.

There are worthwhile challenges ✨:

• Replace deprecated stuffs
• Apply new features
• Update dependencies

PHP: Migrating from PHP 5.6.x to PHP 7.0.x - Manual

[ybelenko]

I'm working on PHP Slim refactoring descripted in #426. In short it's separating generated stubs from user implementation. I'm quite sure that it will be breaking changes without fallback, so maybe we should include both migration to 7.0.x and interfaces/implementation refactoring to the next release?

@ackintosh @wing328 Does it sounds right to you? Should I address both PRs to 4.0.0?

[ackintosh]

Thanks for your great work. It sounds good to me. 👍

The php README still says "Requirements: PHP 5.5 and later"

[wing328]

@jacobweber good catch. Do you mind filing a PR to update it (template)?

[arderyp]

So this issue is still out there. Any hopes of addressing it soon? 5 is long gone by now.

I tried using the phpLegacySupport options, but it seems to do nothing when using the php generator, despite actually producing more strongly typed code when using the php-symfony generator (see this)

EDIT: see #5480

Current progress of migration to PHP 7.x:
