class Emergency {
const Fire = 0;
const Flood = 1;
const NoMilkInFridge = 2;
}
$value = 0; // this is an example of the data you might have
$refl = new ReflectionClass('Emergency');
$enum = $refl->getConstants(); // returns array. key is string, value is integer.
$key = array_keys($enum, $value);
$name = $key[0]; // you now have "Flood"

Initial Description
Proper enumerations in PHP are hard to come by. This uses a class as a pseudo enumeration. Sometimes you'll want to lookup the string name side of the enum when you have the value (ie, you have "1" and you want the string "Flood").
