Bug description: Custom comparison of objects: __equals method
Description:
------------
If a class defines a __equals($other) function, invoke that function on
object comparison. Example:
==========================
class MyClass {
public function __construct($value) {
$this->value = $value;
}
/**
* This function should be invoked on object
* comparison with == or != operators.
*/
public function __equals($other) {
if ($other instanceof MyClass) {
return ((int)$this->value
== (int)$other->value);
} else {
return false;
}
}
private $value;
}
$a = new MyClass(3.14);
$b = new MyClass(3.13);
if ($a == $b) {
echo '$a equals $b';
}
==========================
The comparison of $a and $b should result in the invokation of __equals
function of MyClass. The same should apply to the != (not equals)
operator.
