How to connect to mssql using pdo through PHP and Linux?

Question

I'm trying to for a new PDO connection using the following code.

new PDO("mssql:driver=????;Server={$serverName};Database={$databaseName}", $username, $password, array(PDO::ATTR_PERSISTENT => false, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));

I'm not sure what drivers to use? Or how to install them. I can connect perfectly fine using the mssql_connect function in PHP but I want to use the PDO library instead.

My php.ini settings for mssql are:

ssql

MSSQL Support   enabled
Active Persistent Links     0
Active Links    1
Library version     FreeTDS

Directive   Local Value Master Value
mssql.allow_persistent  On  On
mssql.batchsize 0   0
mssql.charset   no value    no value
mssql.compatability_mode    Off Off
mssql.connect_timeout   5   5
mssql.datetimeconvert   On  On
mssql.max_links Unlimited   Unlimited
mssql.max_persistent    Unlimited   Unlimited
mssql.max_procs Unlimited   Unlimited
mssql.min_error_severity    10  10
mssql.min_message_severity  10  10
mssql.secure_connection Off Off
mssql.textlimit Server default  Server default
mssql.textsize  Server default  Server default
mssql.timeout   60  60

The PDO mssql driver is no more, use sqlsrv (under php windows) or dblib (under php linux)
