PHP判别任何类型的验证码图片

/**
	说明：此类函数是基于优优云图片识别平台的API接口,调用类中的函数可以进行图片识别

	
	类中的公有函数：
		 setSoftInfo($softID,$softKey);				//设置软件ID和KEY
		 userLogin($userName,$passWord);			//用户登录,登录成功返回用户的ID
		 getPoint($userName,$passWord);				//获取用户剩余题分
		 upload($imagePath,$codeType);				//根据图片路径上传,返回验证码在服务器的ID,$codeType取值查看：http://www.uuwise.com/price.html
		 getResult($codeID);						//根据验证码ID获取识别结果
		 autoRecognition($imagePath,$codeType);		//将upload和getResult放到一个函数来执行,返回验证码识别结果
		 reportError($codeID);						//识别结果不正确报错误
		 regUser($userName,$userPassword)			//注册新用户,注册成功返回新用户的ID
		 pay($userName,$Card);						//充值题分，充值成功返回用户当前题分
	
	类中的公有变量：
		 $macAddress='00e021ac7d';					//客户机的mac地址,服务器暂时没有用,后期准备用于绑定mac地址		赋值方法： $obj->macAddress='00e021ac7d'; 
		 $timeOut='60000';							//超时时间,建议不要改动此值									赋值方法： $obj->timeOut=60000;
		 
	函数调用方法：
		 需要先new一个对象
		 $obj=new uuApi;
		 $obj->setSoftInfo('2097','b7ee76f547e34516bc30f6eb6c67c7db');	//如何获取这两个值？请查看这个页面：http://dll.uuwise.com/index.php?n=ApiDoc.GetSoftIDandKEY
		 $obj->userLogin('userName','userPassword');
		 $result=autoRecognition($imagePath,$codeType);
