下面这个程序在你输入id后就把那个id的数据列出来。然后你就可以修改后写入了.
<html
<body
<h1数据库的数据更新</h1
<?
if(isset($id))
{
if(!mysql_connect("localhost","用户名","密码"))
{echo"无法联接数据库";
exit();
}
if(isset($url))
{

fromx=’$fromx’,url1=’$url1’,mess1=’$mess1’,fromx1=’$fromx1’,url2=’$url2’,
mess2=’$mess2’,fromx2=’$fromx2’,url3=’$url3’,mess3=’$mess3’,fromx3=’$fromx3’
where id=’$id’" ;
$result=mysql_db_query("elong",$query); //执行写入
if (!$result)
{echo "发生错误!";
exit();
}
echo "$id 已经更新!
