求php+html增删改查代码

这很简单吧..
$conn=mysql_connect("localhost","root","fengyun666");//数据库ip 用户名 密码
mysql_select_db("xuexiao",$conn); //需要使用的数据库。。

$zi_sql="SELECT * FROM users "; 查询语句(假设你的用户表是users)
$zi_aaa=mysql_query($zi_sql);

while($row = mysql_fetch_array($zi_aaa)){

echo $row[name]; //输出 用户名（你的用户名字段是 name）

}
?>

html页面如下
点击链接

用户名：$v['username'];
分页：

php 页面
global $page,$select_from,$select_limit,$pagenav;
$cmsModel = $this->_getModelByName('CmsModel');
$arr = Array();
$page = empty($_GET["page"])?1:$_GET["page"];
$result1 = $cmsModel->selectt();
$rows = mysql_num_rows($result1);
$page_size = 10;
//分页
$page_count = ceil($rows/$page_size);
if($page <= 1 || $page == '') $page = 1;
if($page >= $page_count) $page = $page_count;
$select_limit = $page_size;
$select_from = ($page - 1) * $page_size.',';
$pre_page = ($page == 1)? 1 : $page - 1;
$next_page= ($page == $page_count)? $page_count : $page + 1 ;
$pagenav .= "第 $page/$page_count 页 共 $rows 条记录 ";
if($page>1){
$pagenav .= "首页 ";
$pagenav .= "前一页 ";
}
if($page < $page_count)
{
$pagenav .= "后一页 ";

}
$pagenav.="　跳到\n";
for($i=1;$i<=$page_count;$i++){
if($i==$page) $pagenav.="$i\n";
else $pagenav.="$i\n";
}
//
$sql = "select * from cms limit $select_from $select_limit";
$result = $cmsModel->query($sql);
$i=0;
$a=($page-1)*$page_size;
while(@$row = mysql_fetch_assoc($result)){
++$i;
$d = $i+$a;
$row['s']=$d;
$arr[]=$row;
}
$num = count($arr);
$this->view->assign("num",$num);
