Bug #50146 property_exists: Closure object cannot have properties
Submitted: 2009-11-11 10:24 UTC Modified: 2009-11-11 18:59 UTC
From: spam04 at pornel dot net Assigned: felipe (profile)
Status: Closed Package: Reflection related
PHP Version: 5.3SVN-2009-11-11 (snap) OS: *
Private report: No CVE-ID: None

property_exists() rejects closures with "Closure object cannot have properties" rather than simply always returning false.

Since closures pass is_object() test, it's hard to avoid this error without testing for "instanceof Closure" as well, which is discouraged in the docs.

Reproduce code:
$obj = function(){}

is_object($obj) && property_exists($obj,'foo');

Expected result:

(either they should not be considered objects, or property_exists should accept any object).

Actual result:
"Closure object cannot have properties"
