I like the proposal except for one thing: the functions returning false in case
of an error. As the next logical function would be "to_bool()", I foresee a lot
of trouble with regards to API design as returning false there either means
successful cast to false or an error while casting. What about changing the
functions to take an $isError variable as a second argument?
$value = to_string(1.2, $isError);
if ($isError) {
...
}
Alternatively one could do the same thing with an $isSuccess variable:
$value = to_string(1.2, $isSuccess);
if (!$isSuccess) {
...
}
Thoughts?
cu,
Lars
