Just go to the OCR.class.php file and change the first <? to <?php

If you have a PHP5 server like Wampserver, it ignores the <? because it is not PHP 5 conform

Hi,

I changed <? to <?php in all php files but I still get the same error as deepa:
Fatal error: Class 'OCR' not found in C:\wamp\www\example.php

I'm grateful for any advice.

ye make sure you have:
<?php //
instead of
<?php//

there should be a space ' ' after the <?php or you won't be able to get anything

Is this PHP OCR solution compatible with .NET framework?
I'm developing a project that need OCR technology and I tried one but it has some problems. Any suggestion?

Here's the solution I've tried:
