#22538 [Opn]: stream filter produces bogus output

ID: 22538 Updated by: moriyoshi@php.net -Summary: stream filters & stream_copy_to_stream combo produces bogus output Reported By: moriyoshi@php.net Status: Open Bug Type: Filesystem function related Operating System: RedHat Linux 8.0 (glibc-2.3.0) PHP Version: 5CVS-2003-03-04 (dev) Assigned To: iliaa New Comment: And, hmm, here's another script to replicate with. By this script, It turned out that the issue isn't stream_copy_to_stream specific. <?php function my_stream_copy_to_stream($fin, $fout) { while (!feof($fin)) { fwrite($fout, fread($fin, 4096)); } } $fin = fopen("Zend/zend.c", "r"); $fout = fopen("/tmp/output", "w"); stream_filter_append($fout, "string.rot13"); my_stream_copy_to_stream($fin, $fout); fclose($fin); fclose($fout); ?> I don't have enough time to fix this right now, so I thank you for taking your time to look at this one ;-) Previous Comments: ------------------------------------------------------------------------ [2003-03-17 14:34:13] moriyoshi@php.net Oops, I forgot to try this one... script 4: <?php $fin = popen("cat Zend/zend.c", "r"); $fout = fopen("/tmp/output", "w"); stream_filter_append($fout, "string.rot13"); stream_copy_to_stream($fin, $fout); fclose($fin); fclose($fout); ?> This results in the same output. ------------------------------------------------------------------------ [2003-03-17 14:30:08] moriyoshi@php.net The bug still persists. $ php script2.php < Zend/zend.c is ok, but it doesn't work with piped stream. Please try the following: $ cat script2.php | php script2.php ------------------------------------------------------------------------ [2003-03-17 12:33:46] iliaa@php.net This bug has been fixed in CVS.

I have no idea about this problem at all.. ------------------------------------------------------------------------ [2003-03-04 12:56:34] moriyoshi@php.net Correcting a typo. wrong: $ php script3.php right: $ cat Zend/zend.c | php script3.php ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
