PHP Version: 5.3.0

New Comment:
I'm sorry for the DOMPDF_TEMP_DIR,
Initially this problem was discovered when using dompdf in this
environment - file_get_contents was a proxy workaround.
I have fully tested this version:
Reproduce code:
---------------
<?php
//temporary location
$resolved_url = tempnam("/tmp", "test_");
//get source
$image=file_get_contents("http://9tree.net/favicon.ico";);
//save it
file_put_contents($resolved_url, $image);
//tests
if(is_readable($resolved_url)) print "file readable, ";
if(filesize($resolved_url)) print "filezise found.";
?>
In Unix/Win32 it works perfectly.
This is only happening in Windows Server 2003 x64 IIS 6.0 where
tempnam("/tmp", "test_") returns something like
"C:\WINDOWS\Temp\tes20FB.tmp".
in the case of filesize i get a warning - "stat failed for
C:\WINDOWS\Temp\tes20FB.tmp ..."
Regards,
Carlos

I have no idea what DOMPDF_XXXX is and how it is used.
Please provide a standalone script I can use to reproduce your problem,
as well as which paths are used by the script.
"- Please note that this problem does not happen in local folder to the
execution base (eg. "tmp_sub_folder/" ) - this only happens in the
system tmp folder in this setup."
It looks like a permission problem to me.

The environment could be the problem here,
I'm using Windows 2003 x64 with PHP x64 via fastcgi.
These are two IIS Servers with load balancer and a separate cluster
that serves the actual run files.
PHP is installed on D:\PHP on each IIS machine.
The problem came up using the library dompdf - it saves document
images content to temporary files in order to build the final pdf
document.
I've reduced the problem to the test code i've attached.
DOMPDF_TEMP_DIR is /tmp and writes to C:\Windows\tmp ...
- Please note that this problem does not happen in local folder to the
execution base (eg. "tmp_sub_folder/" ) - this only happens in the
system tmp folder in this setup.
This is the same setup environment as the one reported in the bug
48852 (about file_put_contents)
Regards,

Cannot reproduce on 2k8, vista and win7. Pls note that I replaced the
my_file_... with the normal file_get_contents function.
Can you paste a working script pls?

Just tested - file_exists() returns false incorrectly too.
I´ve worked around it all with checking for fopen($file, 'r') and
forcing file_get_contents() - it works, file exists, is readable and
returns the content.

Description:
------------
is_readable() returns false for temporary file (just created)
"C:\WINDOWS\Temp\dom373.tmp" and filezise() fails too.
fopen() and get_file_contents() both work for the same file.
as a workaround i'm using fopen() instead of is_readable() and
fseek($fopen_instance, 0, SEEK_END); instead of filesize()
Reproduce code:
---------------
//temporary location
$resolved_url = tempnam(DOMPDF_TEMP_DIR, "dompdf_img_");
//get source
$image=my_file_get_contents("http://9tree.net/favicon.ico";);
//save it
file_put_contents($resolved_url, $image);
//tests
if(is_readable($resolved_url)) print "file readable, ";
if(filesize($resolved_url)) print "filezise found.\n";
die("all done.");
Expected result:
----------------
file readable, filezise found.
all done.
Actual result:
--------------
all done.
