Bug Type: Filesystem function related
Operating System: CentOS 5.3 x86
PHP Version: 5.2.11
New Comment:
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?

Ah fair play, sorry for the confusion. It was an example of what
functions I was using. The real code uses http:// to fetch the required
image.

The thing that doesn't make sense in your bug report is that your
reproduce code just says:
$file = file_get_contents('image.jpg');
file_put_contents('newimage.jpg', $file);
There is no HTTP involved here, so where would the HTTP headers come
from?

But the problem stops occurring as soon as I downgrade to PHP 5.2.10.
No changes are being made to any configuration or extensions either.

Can't reproduce on many servers/platforms. Double check your script or
config, something could be wrong.
