使用PHP从共享文件夹网络复制文件

I encounter an error when copying files inside a directory from another computer in a shared network using PHP. Basically here is the code i am using, the recursive function created by @authorAidan Lister to copy whole directories. It is working on my local machine if I use a local file directory, but when I change it to a directory from another computer it gives me an error concerning permissions.

I am sure that I took care of the permissions concerning folder access because I have gone as far as to allow "Everyone" to be able to have full access to the folder for testing purposes , but it still doesn't work. I am lost and have exhasuted all options I can think of.

PHP is the name of my local machine.

VMSTBOX is the name of the computer with the files i am trying to access.

Also, when I use " chmod("\\VMSTBOX\Users", 0777); "in my PHP code.It also gives me a "permission denied " error. I think this is related to my issue.

I have posted a chunk of my source code below along with the error message below. Thanks for any help

function xcopy($source, $dest, $permissions = 0777)

{
    // Check for symlinks

 if (is_link($source)) {
        return symlink(readlink($source), $dest);
    }

    // Simple copy for a file
    if (is_file($source)) {
        return copy($source, $dest);
    }

    // Make destination directory
    if (!is_dir($dest)) {
        mkdir($dest, $permissions);
    }

    // Loop through the folder
    $dir = dir($source);
    while (false !== $entry = $dir->read()) {
        // Skip pointers
        if ($entry == '.' || $entry == '..') {
            continue;
        }

        // Deep copy directories
        xcopy("$source/$entry", "$dest/$entry", $permissions);
    }

    // Clean up
    $dir->close();
    return true;


$filelocation="\\\VMSTBOX\\Files";

$newfilelocation="\\\\PHP\\VarTemptoCopy";

$status = xcopy($filelocation, $newfilelocation);

CODE ENDS HERE

Here is the error message i keep getting.

"Warning: dir(\VMSTBOX\Files,\VMSTBOX\Files): Access is denied. (code: 5) in C:\xampp\htdocs...."
