php规则验证码读取

<?php//php验证码自动读取//原理：获取验证码图片上每个像素的rgb值，通过判断rgb值获取验证码的01编码；对比编码表获取验证码值define('WORD_WIDTH',8);//验证码文字宽define('WORD_HIGHT',13);//验证码文字高define('OFFSET_X',4);//上边距define('OFFSET_Y',4);//左边距define('WORD_SPACING',7);//验证码间隔class valite{public function setImage($Image){$this->ImagePath = $Image;}public function getData(){return $data;}public function getResult(){return $DataArray;}//获取编码public function getHec(){$res = imagecreatefromjpeg($this->ImagePath);$size = getimagesize($this->ImagePath);//echo $res;exit;$data = array();for($i = 0;
