copy not working

[kayb91]

Hi,

I received the following code from this URL:
http://aidan.dotgeek.org/lib/?file=function.copyr.php

Here is the code:

<?php
/**
Copy a file, or recursively copy a folder and its contents

@author Aidan Lister <[e-mail]>
@version 1.0.1
@ string $source Source path
@ string $dest Destination path
@return bool Returns TRUE on success, FALSE on failure
/
function copyr($source, $dest)
{
// Simple copy for a file
if (is_file($source)) {
return copy($source, $dest);
}

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

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

    // Deep copy directories
    if ($dest !== "$source/$entry") {
        copyr("$source/$entry", "$dest/$entry");
    }
}

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

}

?>

The code is working perfectly on one server, while it fails on another. I cannot figure out what the problem is and why it is failing on the other server.

I am not getting any error messages however. It appears to work great but when going to the new files, most are completely blank. Is there something on the phpinfo page that I should be looking for?

Any help at all would be greatly appreciated.

Thanks,
Annette
