Then we in the program will inevitably design to the algorithm, that is, according to a certain probability to allow users to receive prizes. Let's look at two probability algorithm functions first.
Algorithm One
Copy Code code as follows:
/**
* Full probability calculation
*
* @param array $p Array (' A ' =>0.5, ' B ' =>0.2, ' C ' =>0.4)
Early on these requirements, and then according to the information on the Internet, using a stage-based extraction method, we look at the overall program: The program is completed under the thinkphp framework, using some of the framework of the class library and functions, the following I will explain each, the controller part
The lottery algorithm needs to meet the following requirements:
1. Can control
