No need to initialize the variable $sReturn, because it is in the scope of the function, so "initiliazed" without value by default. And in each iteration the variable is deallocated using "unset", but could also be getting an empty string $sReturn ="". No matter the place, can be in the end or in the beginning of the first foreach.
