最初能否从MySQL数据库获得一个阵列,每当用户看到该数据库时,就会发现其中的一个内容?
原标题:Is it bad to initially get an array from MySQL database, and unset an element of it every time a user has seen it?

I am writing an application which shows a user one thing to vote on, at a time. I have a MySQL table which contains these things. Right now I have it set up so that upon login, I query my database to get a limited number of these things, and then I use PHP to turn that into an array. After a user submits a vote, the thing they ve already voted on is unset from the array. When the new array size is one, I query my database to create a new array. Is this a bad way to do it? Should I instead just query my database to get a new thing for the user to vote on after every time they submit a vote?

感谢任何帮助/建议。

这很可能因为主观性而关闭。

IMHO, 它涉及你想如何运作的问题。 典型的情况是,在标准方案拟订中,我建议把所有东西都装上前面,这样,一旦装满,用户的经验就会非常顺利,没有负荷。

然而,在网络规划中,利用日本宇宙航空研究开发机构或类似的同步手段,积极修改/重建你所需要的阵列,当然是可以接受的,特别是如果最终结果正在以你喜悦的方式运作的话。

Bottom line: Either way will work - it depends on your needs.

减少数据库的互动通常使你的网站具备better。 如果绩效永远会令人关切,这可以帮助那里。 而另一方面,这会使该守则变得更加复杂,可能会影响今后能否维持下去。

归根结底,它是一种贸易。 只要以明确和合乎逻辑的方式完成所有工作,这两种做法都应该是 的。
