如何在类变量中传递值
问题描述：
我正在付款网关payfort上工作，在这里我想通过我的动态价格public $ amount = 7150.00;通过Url请求，但它不起作用。
我是OOPS新手，所以请任何人帮助我。如何在类变量中传递值
静态值工作正常。

答
为了访问（读，修改）一个实例变量（哪个$ amount是），你必须在方法中使用$ this-> amount。
例如。
$this->amount = 1000.00
这是不一样的：
$amount = 1000.00
这将是一个非常不错的主意找一本关于面向对象，并检讨owasp.org榜单前10名的最佳安全实践。具体而言，您的代码需要在使用重定向或将其发送到其他服务之前尽可能严格地验证用户输入。此外，它看起来像你可能已经张贴了一些访问凭据，所以你可能想要改变这些。
您能告诉我们代码的哪部分*不适用于您？ –
我想改变这个静态值：public $ amount = 7150.00;这是在课堂上预定义的。 –
