" 2) "1" 3) "2" The application of lists is quite extensive, just give a few examples: 1. We can use lists to implement a message queue, and we can ensure that the sequence, not as MySQL does not need to be ordered by the order by.2. The use of Lrange can also be very convenient to implement the paging function.3. In the blog system, comments for each blog post can also be stored in a separate list. "

Redis. the following commands belong to the same transaction. Then, enter several commands, which are put into the command queue and not executed immediately. Finally, use the EXEC command to notify Redis that all commands belonging to the same transaction have been input and are now executed. All or all valid commands of the same transaction are executed, or ar

higher than 200 μs, it may be that there are a large number of commands waiting for processing in the redis command queue. As mentioned above, the slow response time may be caused by one or more slow commands. At this time, we can see that the number of command processes per second is significantly decreasing, and even the subsequent commands are completely blocked, this reduces

JavaScript queue, priority queue and cyclic queue, and javascript queue A queue is an ordered set that complies with the FIFO principle.Add new elements to the end of the queue and remove elements from the top.

Array_push () can implement the PHP language stack function. array_push()函数的使用心得1.第一个参数必须是数组。2.所有添加的数组均为索引，即数组下标。3.$num为压入后$stack所含数组元素的个数。4.使用数组的直接赋值也可以实现数组的进栈功能，例如$array$key。$num = array_push($stack"C#""Ruby"array('jsp''Asp'),array('jsp''Asp')); Array_pop () can implement the queue function of the PHP language. arrayarrayarrayNULL。 此外如果被调用不是一个数则会产生一个 Warning。 $stack = array("orange", "banana", "apple", "raspberry");$fruit = array_pop($stack
