基于url参数的动态php类生成

Question

I have an image generating class and a number of sub classes inherited from this. Each sub class generates a different image. I would like to pass the class to generate (or some sort of identifier) in the URL. EG: www.mysite.com/image.php?class=image002 In image.php I could read the class name from the URL, compare this to my database to find the class, then include that class file and generate. I feel that this is not the correct way of doing it. Are there better ways?

Answer 1

Apparently there is nothing wrong with your passing values into url that way especially if these image names are unique and are not sensitive data. unique so that you dont execute the same class with two different images. but you could just append/prepend a random string to the image value. also as hamza said hope they aren't php classes

Answer 2

I am going to go with this answer:

"Instantiate a class from a variable in PHP?"
