$dbhost = localhost;
$dbuser = root; //你的mysql用户名
$dbpass = 123456; //你的mysql密码
$dbname = data; //你的mysql库名
//连接本地数据库
$GLOBALS["conn"] = mysql_connect($dbhost,$dbuser,$dbpass);
//打开数据库
mysql_select_db($dbname,$GLOBALS["conn"]);
?>
2.读取数据库中,某一字段值
//读取一列数据
$sql="select * from ec_admin";
$result = mysql_query($sql,$GLOBALS["conn"]);
printf("用户名: %s
", mysql_result($result,3,"UserName"));
printf("密码: %s
", mysql_result($result,3,"UserPass"));
?>
3,插入某一条数据
$sql="insert into ec_admin(UserName,UserPass) values(liugongxun2,jakemary2)";
$result=mysql_query($sql,$GLOBALS["conn"])or die(mysql_error());
?>
4,while循环
$sql="select * from ec_admin";
$result = mysql_query($sql,$GLOBALS["conn"]);
while($myrow = mysql_fetch_row($result))
{
printf("用户名%s %s密码
",$myrow[1],$myrow[2]);
}
?>
5,do while循环
$sql="select * from ec_admin";
$result = mysql_query($sql,$GLOBALS["conn"]);
if($myrow = mysql_fetch_array($result))
{
do
{
printf("用户名%s %s密码
",$myrow["UserName"],$myrow["UserPass"]);
}while($myrow = mysql_fetch_array($result));
}
?>
6,判断表单是否提交
if ($submit)
{}
?>
