Yii2.0.12升級到PHP7.2可用版本

先說一下Yii框架PHP運行環境的狀況。

Yii2.0.12版本使用\yii\base\Object類，Object做爲類名PHP7.2報錯。

PHP7.2的Yii2最小可用版本爲2.0.13。

提供若干升級的方法。

1. 項目使用Composer管理bower和npm前端資源。

安裝最新版composer-asset-plugin

composer global require "fxp/composer-asset-plugin"

指定類庫更新

composer update yiisoft/yii2 yiisoft/yii2-composer bower-asset/jquery.inputmask

Composer記錄以下

Loading composer repositories with package information
Updating dependencies (including require-dev)
Reading bower.json of bower-asset/yii2-pjax (2.0.7.1)GitHub API limit (60 calls/hr) is exhausted, could not fetch https://api.github.com/repos/yiisoft/jquery-pjax/commits/aef7b953107264f00234902a3880eb50dafc48be. Create a GitHub OAuth token to go over the API rate limit. You can also wait until 2019-02-15 18:54:52 for the rate limit to reset.

Head to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+bw-hz-dev-v14+2019-02-15+1755
to retrieve a token. It will be stored in "/data/home/hanguangchao/.config/composer/auth.json" for future use by Composer.
Token (hidden):
Package operations: 1 install, 2 updates, 1 removal
  - Removing bower-asset/jquery.inputmask (3.3.7)
  - Updating yiisoft/yii2-composer (2.0.5 => 2.0.7): Loading from cache
  - Installing bower-asset/inputmask (3.3.11): Downloading (100%)
  - Updating yiisoft/yii2 (2.0.12 => 2.0.16): Loading from cache
Writing lock file
Generating autoload files

1. 項目配置不經過Composer管理bower和npm的資源

若是你的Yii2作接口應用、微框架，不須要JS，CSS，或自行管理前端資源，在安裝更新的時候能夠移除對bower和npm的資源的依賴。

修改composer.json

"require" : {
      "yiisoft/yii2": "2.0.16"
  },
  "replace": {
      "bower-asset/inputmask": ">=3.2.0"
  }

按需升級

composer update yiisoft/yii2 yiisoft/yii2-composer bower-asset/jquery.inputmask

若是有報錯，通常都是前端資源依賴問題，移除便可。
