"; } $pages = $allPageNums; //总页数 $page = $curPage; //当前页数 $page_len = 9; $page_len = ($page_len%2)?$page_len:$pagelen+1;//页码个数 $pageoffset = ($page_len-1)/2;//页码个数左右偏移量 if($pages>$page_len){ //如果当前页小于等于左偏移 if($page<=$pageoffset){ $init=1; $max_p = $page_len; }else{//如果当前页大于左偏移 //如果当前页码右偏移超出最大分页数 if($page+$pageoffset>=$pages+1){ $init = $pages-$page_len+1; 　　　　　　　　　$max_p = $pages; }else{ //左右偏移都存在时的计算 $init = $page-$pageoffset; $max_p = $page+$pageoffset; } } } else { 　　 　　　　　　$init = 1; 　　　　　　$max_p = $pages; 　　} for($i=$init; $i<=$max_p; $i++) { if ( $i == $curPage ) { $result .= "
$i
"; continue; } $result .= "
$i
"; } // 打印下一页 if ( $allnums > ($offset+$maxrow) ) { $result .= "
