使用php将数据拆分为页面

我想把一个数据表分成几页，这样在搜索记录时就不必向下滚动太多

到目前为止，我的研究已经找到了一些这样做的方法，但所有这些方法都包括大约100多行代码/脚本

现在我想说，我并不懒惰，但我确实想知道这是否真的是必要的，或者是否有一个更短更简单的方法。 假设我可以编写一个Where子句+IF语句，并且在获取或发布少于100行脚本的数据时可能不包括其他内容，我不禁会想，仅仅为了向数据表中添加页面而使用这么长的脚本是不对的

有人知道一些好的链接或简单的脚本吗？或者这是需要那么多脚本的东西？ 干杯

找到了一个解决方案

100行？这可以用不到10:-）JQgrid:Datatable:亲爱的常识先生，你在这里发布的链接指向论坛，你在论坛上解释了一种方法，你发布了这样的链接：“但是，这确实是最低限度的，不包括像减少显示的页面数量和支持额外的where参数这样的重要部分。”这是否意味着如果我的表中有Where子句，这将不起作用？还是会起作用？
