I think we're preaching to the choir at this point. I don't think its a high
priority to anyone who is actually developing PHP. If we want this feature,
then
we should take it upon ourselves to implement and we should all support it
getting
in to a release version.
I'm sure once this is in there then that is when the masses will wonder how
they
ever did without it.

While __toXxx() may more in line with the existing __toString() IMHO __cast()
is more in line with the other magic functions and gettype(). If I could choose
I'd take __cast() and deprectate __toString().

My suggestion is to replace `__cast($to)` with `__toObject($object)` (or even
`__toSelf($object)`). That way, we have a magic method for each type to cast
to,
and we avoid the messy switch/if statements.

I think we all need this badly. It just suits the direction in which the 5.4 is
going.
Regarding same functionality I think it is worth nothing that the conversion to
boolean should be implicit. Otherwise such code could not work:
<?php
function check($response) {
if ( ! $response ) die('error');
}
$resp = new Response();
check($resp->isSuccessful());
check($resp); // this would fail without the cast if the conversion was explicit
?>

This would be very useful in order to be able to define a specific evaluation
method for an object as a boolean, to, for example, simplify if-switches, so
you can just do:
if ($obj)
{
//...
}
Here an example of a class which toggles its own value each time it's evaluated
as a boolean:
class ToggleObj
{
var $val = FALSE;
function __toBool()
{
$ret = $this->val;
$this->val = !$ret;
return $ret;
}
}
$obj = new ToggleObj;
if ($obj)
{
//Does not enter
}
if ($obj)
{
//Now it does
}
Or going further, to make even table rows highlighted:
foreach ($rows as $row)
{
?>
<tr class="<?=$obj?"":"highlighted"?>">
<td><?=$row?></td>
</tr>
<?php
}
Thanks.
