Bug description: objects cast as string explictly require a __toString when
__call is defined
Description:
------------
This produces an error that should not happen. Instead, when you cast an
object to a string that has no __toString defined, it should produce the
objects internal ID. Oddly enough, the behaviour is inconsistent as ...
class A {
public function __call($name, $args) {echo $name;}
}
echo (new A);
seems to work as expected. I can't see how this should behave differently
from dereferencing from a variable.
I guess the behaviour of string casting is undefined for objects that do
not have __toString() defined, so I guess it is debateable if this is
really a bug, or a querky language "feature" ;-)
Note that this will work if one returns a value for __call().
Reproduce code:
---------------
<?php
class A {
public function __call($name, $args) {echo $name;}
}
$a = new A;
echo $a;
?>
Expected result:
----------------
Object id #insert_number_here
Actual result:
--------------
__tostring
Fatal error: Method A::__toString() must return a string value in
/data/test.php on line 21
