PHP PDO 查询如何返回单挑记录

如：select name from user where id = 1
如何获取 name 这个值 怎么办？只有一条数据，

回复讨论(解决方案)

$conn = mysql_connect("localhost","root","");mysql_select_db("mydatabases",$conn);$result = mysql_query("select name from user where id = 1");while ($row = mysql_fetch_array($result)){    echo $row['name'];}

$db = new PDO($dsn, $user, $pass);$rs = $db->query($sql);$a = $rs->fetch(PDO::FETCH_ASSOC);

$db = new PDO($dsn, $user, $pass);$rs = $db->query($sql);$a = $rs->fetch(PDO::FETCH_ASSOC);
