When learning PHP, you will definitely encounter problems with operating MYSQL database, and pagination of the data in the database. Here is a small example to learn about PHP pagination. method.

There are many ways to paginate in PHP. Today we will use a small example to demonstrate this function.

The code is as follows:

$result = "<div class=\"page-num\"><ul class=\"fn-clear\">";

    // 上一页
    if ($offset>0) {
        $result .= "<li>
            <a href=\"".$url.&#39;offset=&#39;.($offset-$maxrow)."\">Prev</a>
        </li>";
    }

    $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 ) {
            $result .=    "<li class=\"on\"><a href=\"".$url.&#39;offset=&#39;.($i*$maxrow)."\" >$i</a></li>";
            continue;
        }

        $result .=    "<li><a href=\"".$url.&#39;offset=&#39;.(($i-1)*$maxrow)."\">$i</a></li>";

    }

    // 打印下一页
    if ( $allnums > ($offset+$maxrow) ) {
        $result .=    "<li>
            <a href=\"".$url.&#39;offset=&#39;.($offset+$maxrow)."\">Next</a>
        </li>";
    }
