PHP version: 5.2.1
PHP Bug Type: Date/time related
Bug description: Incorrect results of DateTime equality check
Description:
------------
The equality check (==) for DateTime objects does not actually check the
properties of the object (i.e. the internally stored date). This is very
counter-intuitive as it does not follow the behavior of user-created
objects or even other internal PHP objects like Exception.
Reproduce code:
---------------
$d1 = new DateTime("2001-01-01");
$d2 = new DateTime("2007-02-28");
print "DateTime Equal? " . var_export($d1 == $d2, true) . "\n";
Expected result:
----------------
DateTime Equal? false
Actual result:
--------------
DateTime Equal? true
