PHP 如何过滤掉 mysql 取出来的数字键名

[DreamCMS]

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

Array
(
[0] => Adams
[LastName] => Adams
[1] => John
[FirstName] => John
[2] => London
[City] => London
)

＋＋＋＋
变成
Array
(

[LastName] => Adams
[FirstName] => John
[City] => London
)
