(tabs, spaces and newlines) and, when it finds a different character, it will upper-case it and switch to REPLACE mode. but that is not really productive because maybe in another script you just forget the break and therefore the warning would be of use. It is important to understand how the switch statement is executed in order to avoid mistakes. Leaving a case empty does not go to default, it drops through to the next case. the only way to get rid of the warning would be to configure the warnings, that phpstorm prints, in this case remove the warning of fall-throughs.

The PHP switch statement simplifies your PHP logic, replacing messy if statements when trying to make simple decisions based on the value of a variable. As you get more confident with your PHP code, your code will get more and more complex.
