html如何调用数据库信息的链接？

<?php
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("yiqicms", $con);
$sql="SELECT * FROM yiqi_article ORDER BY aid DESC LIMIT 10";
$result = mysql_query('set names utf8');
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
echo $row['seotitle'].'<br/>';
}
mysql_close($con);
?>
