Phpredis function Use Summary "classification detail" ___ function

have been using PHP to use Redis, but always feel insecure, simply borrow this time free coherent,

PHP all the operations to the Redis command, almost all the time, including its return value is to stare right, even if the next forget can also directly come to check it ~ Everyone can be assured to use.

Test environment: php:5.5 redis:2.4.6

Redis Five types of data usage scenarios: http://blog.csdn.net/gaogaoshan/article/details/41039581

Tips: For: String, set, sort set, the hash of the increase, change operation, is the same command, but when it changes the operation, timely successful return value is still 0 for: list structure, add or delete to change the free set of methods.
