MS SQL Server (PDO)
If you're using FreeTDS driver and you want to use "charset" parameter then you may have to edit freetds.conf (e.g. /etc/freetds/freetds.conf) and force connection using at least version 7.0 of the protocol.
tds version = 7.0
Charset parameter accepts all encodings supported by iconv (execute iconv --list to show all encodings).

Be careful if you are using dblib with prepared statement, as it will crash if first execution didn't return anything.

on Linux ppc64 / PHP 5.1.2 / freetds-0.64 works well this way:
<?php
// ...
$dbh = new PDO("dblib:host=$hostdb;dbname=$dbname", $usr, $psw);
// ...
?>

when you connect to non standart 1433 port
for win32 use DSN like 'mssql:host=hostname,port;dbname=database'
for FreeTDS and DB-Lib use DSN like 'mssql:host=hostname:port;dbname=database'
