php结合MySQL操作是现在的网站平台的基本配置。这里就讲一下用php进行MySQL的基本操作。

$username = "username";
$password = "password";
$db_name = "db_name";
$link = mysql_connect('localhost', $username, $password);
if (!$link) { die('Could not connect: ' . mysql_error()); }
mysql_select_db($db_name);
mysql_query('set names "utf8"');  #编码设置
