学习PHP,一定会遇到操作MYSQL数据库,而且会对数据库里的数据做分页显示出来的问题,下面写一个小例子学习一下PHP分页的方法。

PHP分页有很多方法,今天我们就用一个小例子演示一下这个功能。

复制代码 代码如下:


$result = "

    ";

        // 上一页
        if ($offset>0) {
            $result .= "

  •             Prev
           
  • ";
        }

        $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            $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
            if ( $i == $curPage ) {
                $result .=    "

  • $i
  • ";
                continue;
            }

            $result .=    "
  • $i
  • ";

        }

        // 打印下一页
        if ( $allnums > ($offset+$maxrow) ) {
            $result .=    "

  •             Next
           
  • ";
        }
