检查该代码是否有任何错误？
<?php
$con=mysqli_connect("localhost","root","","mydb");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysql_query("SELECT * FROM `mytable`");
echo '<ul>';
while (($row = mysql_fetch_assoc($result)) !== false) {
$result= $row['name'];
echo '<li>';
echo '<marquee behavior="scroll" direction="left">Name: '.$result.'</marquee>';
echo '</li>';
}
mysqli_close($con);
?>
我想在marquee中显示mysql字段数据， 请帮帮我。
