// DB 연결
function sql_connect($host, $user, $pass)
{
    global $g4;

    if (strtolower($g4['charset']) == 'utf-8') @mysql_query(" set names utf8 ");
    return @mysql_connect($host, $user, $pass);
}

// DB 선택
function sql_select_db($db, $connect)
{
    global $g4;

    if (strtolower($g4['charset']) == 'utf-8') @mysql_query(" set names utf8 ");
    return @mysql_select_db($db, $connect);
}
