自己写的一个分页函数，可以使用 

<?php 

/**
* DEMO10
* 功能：分页
* author：wenzl
* 分页中心方法DEMO
* 功能智能提供数字分页
* $page 当前页码
* $pageSize 每页数据条数
* $dataTotal 数据总数
* | $number 设置可视分页项数
* | [1][2][3][4][5][6]
*/

	$pageTemp = array();
	for($i=1;$i<=$groupCnt;$i++){
		if($i==1){
			for ($j=1; $j<=$number+1; $j++) {

				$pageTemp[$i][$j] = $k++;

			$k--;
		}else{
			for ($j=1; $j<=$number+2; $j++) {

		$k--;
	}
	$bs = floor($page/$number);

	$step = $ys == 0 ? $bs : $step;

	
	$prevPage = isset($page) && 
	$page <= 1 ? 1 : $page - 1 ;
	
	$nextPage = isset($page) &&
