$result=mysql_query($sql,$GLOBALS["conn"])ordie(mysql_error());
?>
4,php while循环
$sql="select*fromec_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,php dowhile循环
$sql="select*fromec_admin";
$result=mysql_query($sql,$GLOBALS["conn"]);
