<< 1 2 3 4 ... 15 16 17 ... 47 48 49 50 >>

<< 1 2 3 4 5 6 7 ... 47 48 49 50 >>

<< 1 2 3 4 ... 44 45 46 47 48 49 50 >>

（粗体为选中页面）

是否有任何切割器逻辑可以创建这样的缩放分页？我之前已经创建了其中一个，但它最终变成了一团糟的逻辑语句。

我现在使用的语言是 PHP，但如果您有任何语言的示例或提示，将不胜感激。

通过缩放我的意思是当只有几页时。分页显示了这一点。

<< 1 2 3 4 5 6 7 >>

随着页数增长到某个点，分页将停止显示所有数字并开始将它们拆分。

<< 1 2 3 4 ... 47 48 49 50 >>

<< 1 2 3 4 5 6 ... 47 48 49 50 >>

<< 1 2 3 4 5 6 7 8 ... 47 48 49 50 >>

<< 1 2 3 4 .. 7 8 9 ... 47 48 49 50 >>

<< 1 2 3 4 .. 15 16 17 ... 47 48 49 50 >>

<< 1 2 3 4 ... 44 45 46 47 48 49 50 >>

<< 1 2 3 4 ... 47 48 49 50 >>

（注意，实际数字及其前后显示的数量不相关）

抱歉，这里有一堆代码。希望评论足以告诉您它是如何工作的——如果发表评论，我可能会添加更多。
