Description:
------------
The ZEND_CHANGES defines that __toString method whould
be called whenever object is casted to sting. But actually it is
casted to string only during print (echo) operator.
Even the example in ZEND_CHANGES does not work:
class Foo {
function __toString() {
return "What ever";
}
$obj = Foo;
$str = (string) $obj; // call __toString()
echo $obj; // call __toString()
print $str will print the "Object" sring, not the "What ever".
One more code example:
class Integer {
private $value;
function __construct($val) {
$this->value = $val;
}
function __toString() {
return (string)($this->value);
}
}
$i = new Integer(10);
if (10 == $i)
echo '10!!!! :-)';
"10!!! :-)" is not printed.
Expected result:
----------------
When object is accessed in expressions it should be explicitly
casted to sting nor vartype.
