PHP Implementation of Redis encapsulation class complete instance, Phpredis encapsulation Instance _php tutorial

PHP implementation of the Redis encapsulation class complete instance, Phpredis encapsulation instance

The examples in this paper are the encapsulation classes that PHP implements to operate Redis. Share to everyone for your reference, as follows:
