Bug #50152 ReflectionClass::hasProperty behaves like isset() not property_exists
Submitted: 2009-11-11 18:39 UTC Modified: 2009-11-11 18:53 UTC
From: Assigned: felipe
Status: Closed Package: Reflection related
PHP Version: 5.3SVN-2009-11-11 (SVN) OS: Linux
Private report: No CVE-ID:
 [2009-11-11 18:39 UTC]
This change looks to be introduced accidentaly in HEAD, and was MFHd by me times ago. the hasProperty() is currently using the __isset magic method, this doesn't look right from a reflection perspective. It must behaves like property_exists() that doesn't uses the magic stuff.

Reproduce code:

class foo {
	function __isset($a) {
		return 1;

$x = new foo;
$ref = new ReflectionObject($x);

Expected result:

Actual result:
string(1) "b"
