When using readfile() with very large files, it's possible to run into problems due to the memory_limit setting; apparently readfile() pulls the whole file into memory at once. One solution is to make sure memory_limit is larger than the largest file you'll use with readfile(). A better solution is to write a chunking readfile. Here's a simple one that doesn't exactly conform to the API, but is close enough for most purposes: function readfile_chunked ($filename) { $chunksize = 1*(1024*1024); // how many bytes per chunk $buffer = ''; $handle = fopen($filename, 'rb'); if ($handle === false) { return false; } while (!feof($handle)) { $buffer = fread($handle, $chunksize); print $buffer; } return fclose($handle); } ---- Manual Page -- http://www.php.net/manual/en/function.readfile.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48683 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48683&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48683&report=yes Search -- http://master.php.net/manage/user-notes.php
