file exist issue

[rakennedy75]

ok, here is the problem, i am using the file exist function in php and it works part of the time. Basically it works fine in the same directory but if I use it to find a file in another domain on my server, it doesn't work.

Here is what I mean

	$p = "image/test.jpg";
	if(file_exists($p)){
		echo "found";
	} else {
		echo "??";
	}

// The one above works perfect

$p = "http://myOwnDomain.com/image/test.jpg";
if(file_exists($p)){
	echo "found";
} else {
	echo "??";
}

// this one doesn't work

Any ideas on why the second one doesn't work?
I checked the permissions and looks like I have all permissions except write capabilities
Thanks for your help

That's basically potining to the internet, not the filesystem. file_exists doesn't support URL Wrappers until PHP 5.
