note 86554 added to function.header

For large files (100+ MBs), I found that it is essential to flush the file content ASAP, otherwise the download dialog doesn't show until a long time or never. <?php header("Content-Disposition: attachment; filename=" . urlencode($file)); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Description: File Transfer"); header("Content-Length: " . filesize($file)); flush(); // this doesn't really matter. $fp = fopen($file, "r"); while (!feof($fp)) { echo fread($fp, 65536); flush(); // this is essential for large downloads } fclose($fp); ?> ---- Server IP: 209.41.74.194 Probable Submitter: 205.247.136.10 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/86554 Del: integrated -- https://master.php.net/note/delete/86554/integrated Del: useless -- https://master.php.net/note/delete/86554/useless Del: bad code -- https://master.php.net/note/delete/86554/bad+code Del: spam -- https://master.php.net/note/delete/86554/spam Del: non-english -- https://master.php.net/note/delete/86554/non-english Del: in docs -- https://master.php.net/note/delete/86554/in+docs Del: other reasons-- https://master.php.net/note/delete/86554 Reject -- https://master.php.net/note/reject/86554 Search -- https://master.php.net/manage/user-notes.php
