enqueue

PHPmemcache implements message queue instances. Currently, memcache is widely used in server cache. here is an example of implementing message queue waiting in memcache. For more information, see. The principle of memche message queue is now widely

Runstats can compare two different methods for the same thing to find out who is better. We only need to provide two different methods, and runstats is responsible for the rest of the tasks. Runstats is only a measurement of three elements: 1. Time

Queues are often implemented using chained storage. To facilitate operations, we need to maintain a header pointer and a tail pointer, just like sequential storage. For example: It is clear that false overflow will not occur in the chain queue.

　　You can use arrays to implement a queue by imitating the process of implementing stacks using arrays. Front points to the first element of the team, and the value is always the first element of the array a[0]. When the team is out, the front

Resque: enqueue stores data in the redis queue, and the json_decode obtained by the worker is sometimes incomplete (the probability of a high access volume may be higher, not fully verified )! Very depressing. I read a lot of php-ressue code, which

The previous landlord briefly introduced the implementation of the JavaScript data structure stack, http://www.cnblogs.com/qq503665965/p/6537894.html, this time will introduce the implementation of the queue.A queue is a special linear table, except
