分页方法文件名 pagestyle.php

 调用页面代码member.php

<?php
  $sql = "SELECT SQL_CALC_FOUND_ROWS * FROM member WHERE 1";
  $sql = $sql." ORDER BY `mb_no` DESC";
  if (!$page) {
    $page = 1;
  }
  $page_row = ($page-1)*10;
  $sql = $sql." LIMIT ".$page_row." , 10";
  $query=mysql_query($sql);
  $sql2 = "select found_rows() as no";//获得查询出来的记录总数
  $query2=mysql_query($sql2);
  $row2=mysql_fetch_array($query2);
  while($row=mysql_fetch_array($query)){
    echo "……";
    ……
    ……
    等等输出代码，在这里就不做演示了
  }

  $page = $_GET['page'];//获得当前页数
  $total = $row2['no'];//记录总条数
  $phpfile = "member.php";//链接的文件名
  $pagesize = 10;//每页记录数
  $pagelen = 7;//显示7个页数
  
  $code = page($page,$total,$phpfile,$pagesize,$pagelen);
  echo $code['pagecode'];
?>
