Can't copy JPG when using EXIF Data PHP

Question

I've been going at this for about 4 hours now. I've tried several things which I'll explain after the question.

I have all of this EXIF data from the JPG in question (listed below)

What I am trying to do is re-save the JPG into a different folder with a new name. That new name is supposed to be the $data["EXIF"]["UserComment"] after stripping out the "GCM_TAG". This is a barcode that is scanned at a warehouse before the picture is taken.

I am not getting any errors back, I am not getting any warnings back, but the image never shows up. If I change the code to not have the $barcode in it, then suddenly the image shows up. I have tried printing $barcode, I have tried checking what the encoding on the variable is, I have tried using fopen(), file_put_contents() and copy() all to no avail. Each one has the same results. The folder has 777 permissions on it, I can add/remove files using php just fine and have tested that in this code. Any help would be greatly appreciated.

chdir("../test_import_photos");
$directory = getcwd();

echo __FILE__;
print "<br />";
print $directory;
if ($dirhandle = opendir($directory))
{
    while (false !== ($entry = readdir($dirhandle)))
    {
        if($entry == "." || $entry == "..")
        {
            //ignore, its just the folder commands
        }
        else
        {
            $data = exif_read_data($entry,"ANY_TAG",true,false);
            //print "2";
            //print "3";

            $barcode = str_replace("GCM_TAG","",$data["EXIF"]["UserComment"]);

            $filepath = "../test_import_photos_end/X" . $barcode .  ".JPG";
            copy($entry, $filepath);
        }
    }
    closedir($dirhandle);
}

Answer 1

As i see there was an error with the filename (the binary data may corrupts the array()) and copy() just throws an E_WARNING message and must be added to error_reporting(E_ALL); or error_reporting(E_WARNING); to see it.
