Yii2 php init命令

Question

是什么php init命令实际上呢？

在使用此命令创建项目后在cmd中运行此命令时: composer create-project --prefer-dist yiisoft/yii2-app-advanced advanced

我看到很多文件生成在不同的位置,如common,backend,frontend.

init命令只是将目录/环境中的文件复制到项目中

在高级应用程序中,默认情况下您有两个环境(dev和prod),每个环境都有不同的项目配置.

在每个位置,您都有一些配置文件main.php,params.php,main-local.php,params-local.php.文件main.php和params.php适用于所有环境,文件main-local.php和params-local.php是当前环境的配置.

例如,您有实际项目的数据库和用于测试目的的数据库.在这种情况下,您应该在文件main-local.php和params-local.php中为db组件编写不同的配置.

关于这个文件还有一件事.如果要将配置启用到项目,则应在目录/环境中重写它们.因为所有*-local.php文件都包含在git-ignore部分中.因此,您可以在/frontend/config/main-local.php文件中测试不同的配置,如果您成功使用它,可以将其添加到/envinronment/prod/frontend/main-local.php
