#19783 [Com]: A big problem with fread() with PHP4.3.0

ID: 19783 Comment by: r dot prodana at release-it dot de Reported By: nicos@php.net Status: Closed Bug Type: Filesystem function related Operating System: WindowsNT/XP/2000/9x PHP Version: 4CVS-2002-10-06 New Comment: Sorry, you said just read the whole file. What should I do when the file is already bigger than the memory_limit? What's wrong in the following code? $fpWrite = @fopen($localfile, "wb"); $fpRead = @fopen($localfile, "rb"); while (!feof($fpRead)) { fwrite($fpWrite, fread($fpRead, 1024)); } fclose($fpWrite); fclose($fpRead); Previous Comments: ------------------------------------------------------------------------ [2003-01-03 11:15:59] nicos@php.net You have a while(!feof) that does fwrite which is completly wrong. You should READ the whole file (with fread and !feof), then fwrite it. Bogus. Thank for your report. ------------------------------------------------------------------------ [2003-01-03 10:03:49] josh at trollprod dot com I got a similar problem with : apache 1.3.27 PHP 4.2.3 Os : Win NT 4 I do : $fp = @fopen($localfile, "rb"); while (!feof($fp)) { fwrite($file2,fread($file1, filesize($localfile))); } The size are differents on some test file (not all) When the probleme occured the dest file is all the time smaller than the source file ... } fclose($fp); ------------------------------------------------------------------------ [2002-10-13 09:09:20] spic@php.net Sorry, my previous submitted problem is not related to this bug. Please see Bug #19886. ------------------------------------------------------------------------ [2002-10-13 08:52:31] spic@php.net Reopened this bug. readfile() on 4.0, 4.2.4-dev and latest CVS-snapshot (13-Oct-2002 03:27) won't work with large files in Windows. Even $ptfp=fopen($ipoc_passthru_fn,"rb"); while(!feof($ptfp)) { print fread($ptfp,4096); } fclose($ptfp); won't work. Files <100k work fine, larger don't. This error is reproductive on various computers with different Windows-Systems and occurs while trying to pass through PDF-files. ------------------------------------------------------------------------ [2002-10-06 20:56:44] nicos@php.net This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
