Use of undefined constant ERR00 - assumed 'ERR00'

I am having a problem with the encoder

It gives me this error
Use of undefined constant ERR00 - assumed 'ERR00'

i have check the files, they all exist and they are pointing to the right path.

I even tested each file one by one on the web browser URL.

I have also change the folder and all its files to 0777 access rights.

I have even tried BIN mode checked around this forum. It also gave me the same error message.

$frames = array("xxx/xxx/xxx/frames/images01.gif","http://xxx/xxx/xxx/frames/images02.gif");
$framed = array(5,5);
$encode = new GIFEncoder($frames, $framed, 0, 2, 0, 0, 0, "url");
Header('Content-type:image/gif');
echo $encode->GetAnimation();

Any help?

Solved the issue,

Class file has bug

Replace it with this

var $ERR = Array(
'ERR00' => "Does not supported function for only one image!",
'ERR01' => "Source is not a GIF image!",
'ERR02' => "Unintelligible flag ",
'ERR03' => "Does not make animation from animated GIF source",
);

Find the ' '
