note 47910 added to language.oop5.object-comparison

Is it a PHP5 feature or a PHP4 feature? ---- Manual Page -- http://www.php.net/manual/en/language.oop5.object-comparison.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47910 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47910&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47910&report=yes Search -- http://master.php.net/manage/user-notes.php
