用php制作簡單分頁(從數(shù)據(jù)庫讀取記錄)的方法詳解_PHP教程

$conn = mysql_connect('localhost','root','');
mysql_select_db('db_BookStore',$conn);
mysql_query("set names utf8");
if(isset($_GET['page'])) //判斷是否存在page參數(shù),獲得頁面值，否則取1
{
$page = intval($_GET['page']);
}
else
{
$page = 1;
}
$page_size = 2; //最大記錄條數(shù)
$sql = "SELECT count(*) as amount FROM tb_BookInfo";
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
//計算總頁數(shù)
$amount = $row['amount'];
if($amount)
{
if($amount < $page_size){$page_count = 1;}
if($amount % $page_size){$page_count = (int)($amount / $page_size) + 1; }
else{$page_count = $amount / $page_size;}
}
else
{
$page_count = 0;
}
//翻頁鏈接
$page_string = "";
if($page == 1)
{
$page_string .= "首頁 | 上一頁";
}
else
{
$page_string .= "<a href='?page=1'>首頁</a> | <a href='?page=".($page-1)."'>上一頁</a>";
}
$page_string .= "| $page |";
if($page == $page_count)
{
$page_string .= "下一頁 | 尾頁";
}
else
{
$page_string .= "<a href='?page=".($page+1)."'>下一頁</a> | <a href='?page=$page_count'>尾頁</a>";
}
　　 $sql = "select * from table order by id desc limit ". ($page-1)*$page_size .", $page_size";
　 　$result = mysql_query($sql);
　　　　　　 while ( $row = mysql_fetch_row($result) ){
