Answer 1

Don't use any of the MySQL extension commands, they are obsolete and not recommended anymore.

use PDO and prepared atatements.

http://php.net/pdo

$name = '$somethingHere';
$stmt = $db->prepare("Select * from account where account_name = :name");
$stmt->bindValue(':name', $name, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

Answer 2

使用mysql_real_escape_string($account_name)函数。
