note 106349 added to function.readfile

It should be noted that using Apache's "mod_xsendfile" module as an alternative to PHP's native readfile() function does have its drawbacks. With mod_xsendfile, script execution continues immediately after <?php header('X-Sendfile: ' . $file); ?> As such, there is no means by which to delete the file when downloading is complete, determine how much time the download required (or whether or not the download succeeded), track memory usage related to the download, etc. When the aforementioned functionality is required, it seems that readfile() is the only option. Further, and more importantly, failing to terminate script execution immediately after sending the headers (e.g., by returning TRUE within a function) seems to cause mod_xsendfile to fail silently and yield a 404 error. ---- Server IP: 69.147.83.197 Probable Submitter: 76.179.0.31 ---- Manual Page -- http://www.php.net/manual/en/function.readfile.php Edit -- https://master.php.net/note/edit/106349 Del: integrated -- https://master.php.net/note/delete/106349/integrated Del: useless -- https://master.php.net/note/delete/106349/useless Del: bad code -- https://master.php.net/note/delete/106349/bad+code Del: spam -- https://master.php.net/note/delete/106349/spam Del: non-english -- https://master.php.net/note/delete/106349/non-english Del: in docs -- https://master.php.net/note/delete/106349/in+docs Del: other reasons-- https://master.php.net/note/delete/106349 Reject -- https://master.php.net/note/reject/106349 Search -- https://master.php.net/manage/user-notes.php
