note 91606 added to function.flush

Following the speed-up rules from http://developer.yahoo.com/performance/rules.html in the topic "Flush the Buffer Early" with ob_start() will output headers early and thereby corrupt error handling events extended with eg. FirePHP that will trigger something like; "Exception thrown within the exception handler. Message: Headers already sent in on line 0. Cannot send log data to FirePHP." or "Exception thrown without a stack frame in Unknown on line 0". So use </head><?= ob_flush(); =?><body> instead to invoke this rule/recommendation with ob_start(); to make it work. ---- Server IP: 203.121.145.220 Probable Submitter: 118.173.2.66 ---- Manual Page -- http://www.php.net/manual/en/function.flush.php Edit -- https://master.php.net/note/edit/91606 Del: integrated -- https://master.php.net/note/delete/91606/integrated Del: useless -- https://master.php.net/note/delete/91606/useless Del: bad code -- https://master.php.net/note/delete/91606/bad+code Del: spam -- https://master.php.net/note/delete/91606/spam Del: non-english -- https://master.php.net/note/delete/91606/non-english Del: in docs -- https://master.php.net/note/delete/91606/in+docs Del: other reasons-- https://master.php.net/note/delete/91606 Reject -- https://master.php.net/note/reject/91606 Search -- https://master.php.net/manage/user-notes.php
