    //分页判断
    $lastpage = ceil($page_array['total'] / $page_array['dispage']); //最后一页
    $page_array['now_page'] = min( $lastpage , $page_array['now_page'] );//比较当前页数和最后一页
    $prepage = $page_array['now_page'] - 1;//上一页
    $nextpage = ($page_array['now_page'] == $lastpage ? 0 : $page_array['now_page'] + 1 );//下一页
    $firstcount = ($page_array['now_page']-1) * $page_array['dispage'];
    if( $lastpage  
    //首页
    if($prepage){
        $page_array[]="首页";
