Status: Open
Bug Type: Filesystem function related
Operating System: CentOS 5.3 x86
PHP Version: 5.2.11
New Comment:
It would be really helpful if you could create an actual script that
reproduces this. It isn't until the 8th comment on this bug that we
learn that it only happens if you are doing a whole bunch of them
together. Your original reproducing script not only didn't have any
network component, but it also didn't have anything about multiple
connections.
How are you doing these multiple connections? Just a big loop around
file_get_contents? The best way to report a bug is to simplify your
problem down into a script that we can run ourselves and see the
problem. If we can see it, we can fix it. Otherwise we are guessing as
to what might be happening on your end.

I was thinking about a bug the curl stream wrapper, but no. I can't
reproduce this problem either, no matter the web server/OS/platform.

Sure, here it is:

Can you show us your configure line too please?

That works fine, but it's a single file. The script I'm running is
fetching up to 80 images from a remote source (based on the same
network) and compiling into a PDF.
I rebooted the server a few minutes ago and tried again... The script
completed no problem, fetched all images and compiled into a PDF. So I
tried again, but it failed half way through. The reason it gave was
imagecreatefrompng complaining one of the PNG files was corrupt. I
checked the PNG file and it contained the header information:
HTTP/1.1 200 OK
Date: Sun, 20 Sep 2009 22:03:29 GMT
Server: Apache
Last-Modified: Tue, 15 Sep 2009 14:04:55 GMT
Accept-Ranges: bytes
Content-Length: 883
Cache-Control: max-age=2592000
Expires: Tue, 20 Oct 2009 22:03:29 GMT
Connection: close
Content-Type: image/png
�PNG
There were other files in the same folder (the /tmp folder) that were
created as part of the same job, which compiled into temporary PNGs and
JPEGs no problem, with no header information. This has only started
happening since PHP 5.2.11.
I thought this was a bug since if I recompile Apache with PHP 5.2.10
instead leaving the configuration in tact, and try again, the script
completes, again and again no problem. It never fails.
Is there any reason why PHP is adding header info to files instead of
just the file contents?

And you can reproduce it with a 2-liner like that? I can't on my Linux
box.
Try this on your system:
$img = file_get_contents('http://slowgeek.com/flat.png');
file_put_contents('flat.png',$img);
run it a couple of times from the command line. Is your flat.png ever
corrupted?
