The expression
$di of type string|null is loosely compared to true ; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.
In PHP, under loose comparison (like For '' == false // true
'' == null // true
'ab' == false // false
'ab' == null // false
// It is often better to use strict comparison
'' === false // false
'' === null // false

The break statement is not necessary if it is preceded for example by a return statement:
If you would like to keep this construct to be consistent with other case statements, you can safely mark this issue as a false-positive.
