Sync settings with composer? Permanently deleted user Created July 31, 2017 22:23 I received this notification in PhpStorm 2017.2. Can anyone explain the question and what are the ramifications?
See https://www.jetbrains.com/help/phpstorm/composer.html - the part about "Synchronize IDE settings with composer.json"
I found some information in this section https://www.jetbrains.com/help/phpstorm/using-the-composer-dependency-manager.html#setting-up-an-external-composer-project under item 3.
It appears enabling this will automatically detect the PHP language level and configure project Source and Test roots based on the configuration from composer.json.
