A simple php class for verification code identification.

• Import the class file and create the instance of the class

include "VC/VC.php";
$object = new VerifyCode();

• Teach the program with some image sample

$object->Init_Image("VC/1.jpg", array('g', '4', 'J', 'p'));
$object->Init_Image("VC/2.jpg", array('B', 'H', 'd', '7'));
$object->Init_Image("VC/3.jpg", array('T', 'F', '5', 'H'));
...

• Identify the unknown verify code

echo $object->Recognize_Image("verifyCode.jpg");

• It's just a identification program for very simple verify code.
• If want to speed it up, you can write a cache file instead of teaching the program everytime.
