[PHP] variable scope -- unsetting vars inside functions

[Michael A. Smith]

When a function finishes execution does it automatically clean up its local
variables or should I manually unset() them? For example:

function do_something() {
    $local_var = 'something really big...';
    return true;
}

Does $local_var immediately vanish from existence when do_something finishes
executing?

Thanks!
