note 84216 added to function.headers-sent

If you want to use headers_sent() to test if any HTML output has been generated, like in an error handler routine, then you should call ob_flush() before invoking headers_sent(). Otherwise it may return FALSE even when some output has already been generated. ---- Server IP: 213.249.64.162 Probable Submitter: 82.139.115.2 ---- Manual Page -- http://www.php.net/manual/en/function.headers-sent.php Edit -- https://master.php.net/note/edit/84216 Del: integrated -- https://master.php.net/note/delete/84216/integrated Del: useless -- https://master.php.net/note/delete/84216/useless Del: bad code -- https://master.php.net/note/delete/84216/bad+code Del: spam -- https://master.php.net/note/delete/84216/spam Del: non-english -- https://master.php.net/note/delete/84216/non-english Del: in docs -- https://master.php.net/note/delete/84216/in+docs Del: other reasons-- https://master.php.net/note/delete/84216 Reject -- https://master.php.net/note/reject/84216 Search -- https://master.php.net/manage/user-notes.php
