Php Live server获取结果花费的时间太长

从上个月开始工作，我尝试了很多从谷歌得到的解决方案，但没有得到任何帮助。代码在localhost上运行得既完美又快速。但不在实时服务器（VPS主机）上。请访问链接，看看它需要永远过滤14000个手机号码在DND和非DND号码。但在我的本地主机上，完成相同的过程只需要大约20秒。我不明白原因，也没有时间在这上面浪费更多。请尽快提供您的解决方案

PS：本网站使用GoDaddy VPS托管，内存为4GB

下面是代码

控制器（filter.php）

从远处看这辆车，我们无法告诉你发动机出了什么问题。提供一些代码和数据库模式。虽然您显然感到沮丧，但我认为不愿意在这方面“浪费”时间，并期望我们在这方面浪费时间是不合理的。主要的问题是你没有给出任何关于实际问题本身的细节。如果您不能花时间实际描述背景和问题，那么其他人将无法帮助您。请尝试为相同的问题创建存储过程。我可以帮你。live数据库上的数据比localhost数据库上的数据多吗？服务器上的数据库非常大。差不多有200000个电话号码。。给定的号码需要与数据库表中的手机号码匹配，并获取相应过滤的DND和NON-DND。。该网站在本地主机上运行良好。。但在实时服务器上，它正在产生问题。。VPS主机有问题吗？？对于相同的工作，4GB内存是否更少？
