You gave too abstract example. Personally I haven't seen such
construction. Most people, IMO, would rather do:
$string = '';
if( !((bool) $string) ) { die("oops"); }
Besides, I think, it's against the programming convention :)

Well... doing (string)((int)((string) '153 foo')); you won't get '153
foo' as the result. So where's the "consistent behavior"? ;)

You need to be able to get consistent behavior regardless of the cast,
not everyone is just printing the output.
$false = false;
if ((string)$false)) { die("oops"); }
If the typecast made it return "false" then you'd see the oops here.

One more thing.

May I ask, why? When casting '153 foo' to int you get 153. Why, when
casting 'false' (or 'FALSE', whatever) you get 1 (true), not 0 (false)?
PHP is a script language, it should the difference, IMO.)

Ok about string. But what about casting to bool (same problem).)

false has to be an empty string to correctly evaluate to false. No bug
here.

You missunderstood me. The cast of a bool(false) is "" but cast of a
bool(true) is "1". IMO it should be "false" and "true", or, at least "0"
and "1".)
