Google App Engine：警告：Cloud SDK不再附带PHP 5.4的运行时

Question

I'm receiving this error when trying to deploy locally using Google App Engines's sdk (PHP 7)

dev_appserver.py app.yaml 

Returns

WARNING: The Cloud SDK no longer ships runtimes for PHP 5.4.  Please set your runtime to be "php55".

This is my .yaml file

runtime: php
env: flex

runtime_config:
  document_root: public

# Ensure we skip ".env", which is only for local development
skip_files:
  - .env

env_variables:
  # Put production environment variables here.
  APP_LOG: errorlog
  APP_KEY: :XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
  STORAGE_DIR: /tmp 

It works fine using PHP 5+

runtime: php55
api_version: 1

My sdk components are up to date.

I'm not finding anyone having this issue. Wondering if I should just re-install the sdk.

Answer 1

dev_appserver.py does not run in the App Engine flexible environment.

From the standard environment Running the local development server :

Note: dev_appserver.py does not run in the App Engine flexible environment.

From the flex environment Running locally :

You run your application locally with the native development tools that you usually use.

Answer 2

The php option is probably still around for backward compatibility since 5.4 used to be supported. Use php55 .

From the August 14, 2015 - Version 1.9.25 Release notes:

• Development server no longer supports the "php" runtime. This will result in a Runtime Error. Please use "php55" instead.

And from the app.yaml Syntax table:

runtime

Required. The name of the App Engine runtime environment used by this application. To specify PHP, use php55.

 runtime: php55 

Update:

The above applies to the standard environment only, but since this is a flexible environment config @btaylor507's answer is better.
