快速提问,可能很简单,也许不是。我不熟悉PHP,HTML或MySQL,但我正在考虑它。以下是我正在使用的示例页面:http://www.djdarby.com/sorter.php。我正在展示一张19600年的桌子,其中包含两个领域,艺术家和歌曲。问题是它加载速度非常慢,我不知道在哪里指向手指。也许我的查询太简单了,或者我一次加载太多。这是代码,因为PHP在页面源上变得不可见。有没有更快的方法输出这些数据?
编辑:我忘了提及我正在使用javascript制作表格,TinyTable是准确的。
编辑NUMERO DOS:我制作了sorter2.php,它似乎加载得更快,这是一个javascript问题吗?

在查询字符串中追加“LIMIT $ start,$ stop”,尽量不要在一个页面中使用太多记录
