php – Check if a file exists in Yii

Questions:

I am creating a bunch of modules that all extend a base module. However, some actions need to override the base view. In that case, I’d like to check if the new module has a view in its structure. If it does, use that view, and otherwise use the base one. Now, my question:

Is there a way to check if a file exists in Yii, using the typical alias structure application.views.user.basic_view without using or importing it?

How to&Answers:

Try use Controller or CWidget method getViewFile

Answer:

Untested, but what’s about resolving the alias to a path and then check this…

 echo is_file(Yii::getPathOfAlias('application.views.user.basic_view'))?'yes':'no';
