Ok, why this won't work? I want to check if file_exists on mapped drive. I have tried several ways and readed php manual but can't get it work.

I have tried for example these:
(aslo tried without "getcwd()")

if (file_exists (getcwd()."W:\folder1\folder2\file.txt"))
{
Header("Location: W:\folder1\folder2\file.txt");
}


if (file_exists (getcwd()."W:\\folder1\\folder2\\file.txt"))
{
Header("Location: W:\\folder1\\folder2\\file.txt");
}


if (file_exists (getcwd()."W:/folder1/folder2/file.txt"))
{
Header("Location: W:/folder1/folder2/file.txt");
}

if (file_exists (getcwd()."W://folder1//folder2//file.txt"))
{
Header("Location: W://folder1//folder2//file.txt");
}

if (file_exists (getcwd()."//computername/folder1/folder2/file.txt"))
{
Header("Location: //computername/folder1/folder2/file.txt");
}



If I put those in <A HREF=" ">link</A> some will work. In link those will work but PHP can't find the file from mapped network drive... why?

you can not mapp to a local drive like this. The browser accepts only urls. (localhost i.e)

Remember that, like Oliver noted, you can only use URLs. Such as:

http:\\localhost\filename_here.txt

The only way you can check on files existing is if they're in the webserver directory (or subdirectory).

If you could map a network drive to a folder in one of those directories, that would work (though I don't even know if its possible and that would be a godawful security risk).

Short Answer: No.

Long Answer: Too much of a security risk to bother with.

I would suggest another language for this, perhaps javascript. PHP won't do what you're looking for here.

Why not simply use include() function?

All you need is to display the content of that page to the user, right? Since it is outside the webroot, you can only include it.

ie:

if (file_exists (getcwd()."W:\\folder1\\folder2\\file.txt")) {
    inlude("W:\\folder1\\folder2\\file.txt");
}
