请帮助我如何仅显示5页码..

SET：
$adjacents = 3
$total_pages= 22
$limit= 8
Total Records from Database: 171
预期输出：
PREVIOUS 1 2 3 4 ... 22 NEXT
PREVIOUS 1 .. 5 6 7 8 ... 22
PREVIOUS 1 .. 19 20 21 22 NEXT
但是，我无法获得预期的输出.. 我可以花一些时间来分析如何控制它产生的页码。
当前输出
PREVIOUS 1 2 3 4 5 6 7 8 9 ... 21 22 NEXT
PREVIOUS 1 2 ... 6 7 8 9 10 11 12 ... 21 22 NEXT
PREVIOUS 1 2 ... 14 15 16 17 18 19 20 21 22 NEXT
