Not to the topic, but there should NEVER an else after a return/exit/croak/die.
A return/die/exit/croak will end the current scope immediately, making the else obfuscating the code that follows, as the code after the else block will never be executed if the if branch is taken.
If I were a code reviewer, that code would be vetoed.
