note 107181 added to function.is-a

As of PHP 5.3.9, is_a() seems to return false when passed a string for the first argument. Instead, use is_subclass_of() and, if necessary for your purposes, also check if the two arguments are equal, since is_subclass_of('foo', 'foo') will return false, while is_a('foo', 'foo') used to return true. ---- Server IP: 208.69.120.55 Probable Submitter: 74.104.45.177 ---- Manual Page -- http://www.php.net/manual/en/function.is-a.php Edit -- https://master.php.net/note/edit/107181 Del: integrated -- https://master.php.net/note/delete/107181/integrated Del: useless -- https://master.php.net/note/delete/107181/useless Del: bad code -- https://master.php.net/note/delete/107181/bad+code Del: spam -- https://master.php.net/note/delete/107181/spam Del: non-english -- https://master.php.net/note/delete/107181/non-english Del: in docs -- https://master.php.net/note/delete/107181/in+docs Del: other reasons-- https://master.php.net/note/delete/107181 Reject -- https://master.php.net/note/reject/107181 Search -- https://master.php.net/manage/user-notes.php
