note 115698 added to function.exif-read-data

Hope this helps someone. ---- Server IP: 72.52.91.14 Probable Submitter: 119.151.34.11 ---- Manual Page -- http://php.net/manual/en/function.exif-read-data.php Edit -- https://master.php.net/note/edit/115698 Del: integrated -- https://master.php.net/note/delete/115698/integrated Del: useless -- https://master.php.net/note/delete/115698/useless Del: bad code -- https://master.php.net/note/delete/115698/bad+code Del: spam -- https://master.php.net/note/delete/115698/spam Del: non-english -- https://master.php.net/note/delete/115698/non-english Del: in docs -- https://master.php.net/note/delete/115698/in+docs Del: other reasons-- https://master.php.net/note/delete/115698 Reject -- https://master.php.net/note/reject/115698 Search -- https://master.php.net/manage/user-notes.php
