if you are wanting to know if a string is set and is not null, you would be best to use strlen()
instead of empty() to avoid the typemorph nonsense (in particular, "0" == false) while
still preserving efficiency and logical presentation, i.e.:
if (strlen($string)) {
echo "string was set to ".$string;
} else {
echo "string was not set";
}
