fopen permission denied when opening a file via IP

[chalky_dev]

I am hoping someone can help me or shed some light on an issue I am facing.

I am running into a permission denied issue with trying to access a file via IP. When I access the file through the DNS name everything is fine. The problem is that on the production system I can't use the DNS name.

Here is some sample code to show you what I am doing: (these are just sample sharenames and IPs, but I have verified that the share IP is correct)

$file = '\\\\mysharename\files\sample.txt';
echo $file.'<br>';
if(@fopen($file, 'r'))
{
	echo 'file exists <br>';
}
else
{
	$error = error_get_last();    

	echo $error['message'];

echo '<br>Does not exist';
}
$file = '\\\\10.10.0.1\files\sample.txt';
echo $file.'<br>';
if(@fopen($file, 'r'))
{
	echo 'file exists <br>';
}
else
{
	$error = error_get_last();    

	echo $error['message'];

echo '<br>Does not exist';
}

The output:
\mysharename\files\sample.txt
file exists

\10.10.0.1\files\sample.txt
fopen(\10.10.0.1\files\sample.txt) [function.fopen]: failed to open stream: Permission denied
Does not exist

This is a total shot in the dark, but you can try the SMB Stream Wrapper class, so you can use smb://

Find the file at phpclasses.

Thanks big.nerd. This was a huge help. Using this now returns saying the file exists.

Now for some reason if I try and get the contents from the file it does not return the contents. It thinks the file is empty.

Here is more code of what I am doing:

$file = 'smb://10.10.0.1/files/sample.txt';
if($handle = @fopen($file, 'rb'))
{
	echo '<br><br>file exists <br>';
}
while (!feof($handle)) 
{ 
	echo fgets($handle, 4096); 
} 

fclose($handle);

The the output is blank.

If I choose to use readfile() and print the length I get 0 return.
