note 85222 added to function.header

If you suddenly get an error "headers already sent" on a page that was previously working or looks OK, check for a blank line. I spent a little while until I spotted: <? some code ?> <<<<< (BLANK LINE IN HERE) <? header("Location:foo_bar.php")' ?> ---- Server IP: 203.88.112.190 Probable Submitter: 58.96.40.116 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/85222 Del: integrated -- https://master.php.net/note/delete/85222/integrated Del: useless -- https://master.php.net/note/delete/85222/useless Del: bad code -- https://master.php.net/note/delete/85222/bad+code Del: spam -- https://master.php.net/note/delete/85222/spam Del: non-english -- https://master.php.net/note/delete/85222/non-english Del: in docs -- https://master.php.net/note/delete/85222/in+docs Del: other reasons-- https://master.php.net/note/delete/85222 Reject -- https://master.php.net/note/reject/85222 Search -- https://master.php.net/manage/user-notes.php
