note 55747 added to function.isset

In PHP4, the following works as expected: if (isset($obj->thing['key'])) { unset($obj->thing['key']) ; } In PHP5 however you will get a fatal error for the unset(). The work around is: if (is_array($obj->thing) && isset($obj->thing['key'])) { unset($obj->thing['key']) ; } ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55747 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55747&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55747&report=yes Search -- http://master.php.net/manage/user-notes.php
