实现代码

if($rows == 0){ return $data = array( 'page' => $page,'MaxPage' => $MaxPage,'MinPage' => $MinPage,'ServerPage' => $ServerPage,'PageData' => $PageData,'PageShowData' => $PageShowData ); } //得到最大<a href="https://www.jb51.cc/tag/fenye/" target="_blank" class="keywords">分页</a>和最小<a href="https://www.jb51.cc/tag/fenye/" target="_blank" class="keywords">分页</a> $MaxPage = intval($rows / $num); $double = $rows % $num; if($double > 0.000000001) { $MaxPage += 1; } $MinPage = 1; $ServerPage = 1; //得到<a href="https://www.jb51.cc/tag/yema/" target="_blank" class="keywords">页码</a>的全部项目 for($i = 1; $i <= $MaxPage; $i++ ){ $PageData[$i] = $i; } //对<a href="https://www.jb51.cc/tag/yema/" target="_blank" class="keywords">页码</a>进行正确性改正 if($page < $MinPage){ $page = 1; } if($page > $MaxPage){ $page = 1; } /*<a href="https://www.jb51.cc/tag/shengcheng/" target="_blank" class="keywords">生成</a><a href="https://www.jb51.cc/tag/xianshi/" target="_blank" class="keywords">显示</a>的<a href="https://www.jb51.cc/tag/yema/" target="_blank" class="keywords">页码</a><a href="https://www.jb51.cc/tag/biaoqian/" target="_blank" class="keywords">标签</a>*/ //<a href="https://www.jb51.cc/tag/shengcheng/" target="_blank" class="keywords">生成</a>左侧的<a href="https://www.jb51.cc/tag/daima/" target="_blank" class="keywords">代码</a>快 if($page == $MinPage){ $PageShowData[1] = $page; } if($page > $MinPage){ $PageShowData[1] = $MinPage;

// $PageShowData[2] = $page - 1; // <<
$PageShowData[2] = '<<'; // <<
if($page -2 > $MinPage ){
$PageShowData[3] = $page - 2;
$PageShowData[4] = $page - 1;
}elseif($page -2 == $MinPage){
$PageShowData[3] = $page - 1;
}
//确定选中的页码代码
$PageShowData[count($PageShowData) + 1] = $page;
}
$COUNT = count($PageShowData) + 1;
//生成右侧的代码
if($page == $MaxPage){
return $data = array(
'page' => $page,'PageShowData' => $PageShowData
);
}
if($page < $MaxPage) {
if($MaxPage - $page >= 2){
$j = 1;
for($i = $COUNT; $i <= $length ; $i++){
$PageShowData[$i] = $page + $j;
$j ++;
if($PageShowData[$i] == $MaxPage -1){
break;
}
}
}

    $COUNT = count($PageShowData) + 1;

// $PageShowData[$COUNT] = $page + 1; //>>
$PageShowData[$COUNT] = '>>';
$PageShowData[$COUNT + 1] = $MaxPage;

    //得到选中的参数
    $ServerPage = $PageShowData[$COUNT-1] + 1;
    if($ServerPage > $MaxPage){
      $ServerPage = 1;
    }

    return $data = array(
      'page' => $page,'PageShowData' => $PageShowData
    );
  }

}
