想写一个php+mysql 代码

想写一个php+mysql 代码 可以连接MYSQL 把裹面表的资料打印在一个表格上显示出来
我自己上网找了一个但是就是运行不了会出现Trying to get property of non-object in
server:localhost
server_user:root
server_passwd:密码空
database:bus_stop
table:one(3行)
以下是代码
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "bus_stop";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT id, firstname, lastname FROM one";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
echo "<table><tr><th>bus_no</th><th>no</th><th>ssid</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>".$row["bus_no"]."</td><td>".$row["no"]." ".$row["ssid"]."</td></tr>";
}
echo "</table>";
} else {
echo "0 results";
}
$conn->close();
?>

Answer 1

mysql_connect("localhost","db_username","db_userpass");
mysql_select_db("db_name");
$sql = mysql_query("select title from biao");
$row = mysql_fetch_array($sql);
echo $row["title"];

这样就行了
