Assuming your language level is PHP >=7.4, make sure the Closure can be converted to arrow function inspection is enabled in settings
https://www.jetbrains.com/help/phpstorm/php-closure-can-be-converted-to-arrow-function.html
Then alt/option + Enter whenever the cursor is over the Closure, and the option for converting to a short Closure should be available.

Old post but I just ran into this problem. In the latest PHPStorm 2021.3.1 I had to set the language level. Out of the box it was set at version 7.3. I had tried to manually create a arrow function and got an error telling me I had to have at least 7.4 , which was confusing since I only have 8.1 installed on my system. I thought PHPStorm would have auto detected this but apparently it doesn't.
Hope this helps someone out if they run into this.
