In PHP, why do true cast 1 and false cast an empty string?

Question

Boolean TRUE is converted to the string "1". Boolean FALSE is converted to "" (empty string).

Why doesn't FALSE add the value "0"?

If you added to int and then to string it prints 0 ..

$x=false;
print (string)(int)$x;

Fingerprints 0. You can, of course, omit the string type created by printing anyway.
