PHP错误 急，在线等！！

Fatal error: main() [<a href='function.main'>function.main</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Car" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in D:\TsbGameWebSystem\back_car.php on line 15

这是什么错误？为什么会出现呢？如何避免呢？ 感谢各位高手帮我解惑！
虽然不是很清楚为什么。。 但是同样代码在另一台机器上运行却很正常 无致命错误。
不知是否为 php.ini配置文件的问题啊~ 知情者麻烦将答案发送至我的邮箱

The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Car" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in D:\TsbGameWebSystem\back_car.php on line 15

程序尝试去解释一个对像的方法或属性，请确认你要操作的类里在调用"loaded_before_unserialize()"之前已定义”Car”，或提供一个__autoload()的方法加载类的定义，在D:\TsbGameWebSystem\back_car.php 的行15

意思就是说你调用Car这个属性或方法之前没有对他进行定义！
