note 54295 added to function.readfile

In response to flowbee@gmail.com -- When using the readfile_chunked function noted here with files larger than 10MB or so I am still having memory errors. It's because the writers have left out the all important flush() after each read. So this is the proper chunked readfile (which isn't really readfile at all, and should probably be crossposted to passthru(), fopen(), and popen() just so browsers can find this information): <?php function readfile_chunked($filename,$retbytes=true) { $chunksize = 1*(1024*1024); // how many bytes per chunk $buffer = ''; $cnt =0; // $handle = fopen($filename, 'rb'); $handle = fopen($filename, 'rb'); if ($handle === false) { return false; } while (!feof($handle)) { $buffer = fread($handle, $chunksize); echo $buffer; flush(); if ($retbytes) { $cnt += strlen($buffer); } } $status = fclose($handle); if ($retbytes && $status) { return $cnt; // return num. bytes delivered like readfile() does. } return $status; } ?> All I've added is a flush(); after the echo line. Be sure to include this! ---- Manual Page -- http://www.php.net/manual/en/function.readfile.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54295 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54295&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54295&report=yes Search -- http://master.php.net/manage/user-notes.php
