note 117355 added to function.exif-read-data

I was needing to use exif_read_data() to read out the orientation flag, only to find that the webhost didn't have the exif extension available for use. Instead, I hacked up a regex that worked fairly well as a replacement <?php $orientation = 1; if (function_exists('exif_read_data')) { $exif = exif_read_data($filename); if (isset($exif['Orientation'])) $orientation = $exif['Orientation']; } else if (preg_match('@\x12\x01\x03\x00\x01\x00\x00\x00(.)\x00\x00\x00@', file_get_contents($filename), $matches)) { $orientation = ord($matches[1]); } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 131.203.245.222 ---- Manual Page -- http://php.net/manual/en/function.exif-read-data.php Edit -- https://master.php.net/note/edit/117355 Del: integrated -- https://master.php.net/note/delete/117355/integrated Del: useless -- https://master.php.net/note/delete/117355/useless Del: bad code -- https://master.php.net/note/delete/117355/bad+code Del: spam -- https://master.php.net/note/delete/117355/spam Del: non-english -- https://master.php.net/note/delete/117355/non-english Del: in docs -- https://master.php.net/note/delete/117355/in+docs Del: other reasons-- https://master.php.net/note/delete/117355 Reject -- https://master.php.net/note/reject/117355 Search -- https://master.php.net/manage/user-notes.php
