//数据库连接
@mysql_connect("localhost","root","root123") or die("连接数据库失败：".mysql_error());
mysql_select_db("test");
mysql_query("set character set 'gbk'");
//每页显示的留言数
$pagesize = 4;
输出当前页数据
//确定当前页数 $p 参数
$p = $_GET['p']?$_GET['p']:1;
//数据指针
$offset = ($p-1)*$pagesize;
//查询本页显示的数据
$query_sql = "SELECT * FROM guestbook ORDER BY id DESC LIMIT $offset , $pagesize";
$result = mysql_query($query_sql);
//循环输出
while($gblist = mysql_fetch_array($result)){
echo '<a href="',$gblist['nickname'],'">',$gblist['nickname'],' ';
echo '发表于：',date("Y-m-d H:i", $gblist[createtime]),'<br />';
echo '内容：',$gblist['content'],'<br /><hr />';
}
确定当前页参数 $p 中，使用了一个三元运算符：
$p = $_GET['p']?$_GET['p']:1;
