要把源代码贴出来啊，不过根据提示信息大概也能判断出来
<?php
$con = mysql_connect("localhost", "hello", "321");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person WHERE Lastname='Adams'";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_array($result));

mysql_close($con);
?>

你的问题就是 sql 语句不正确，导致mysql_query返回了false
