This is because PDO treats "localhost" host specially:

Note: Unix only: When the host name is set to "localhost", then the connection to the server is made thru a domain socket. If PDO_MYSQL is compiled against libmysqlclient then the location of the socket file is at libmysqlclient's compiled in location. If PDO_MYSQL is compiled against mysqlnd a default socket can be set thru the pdo_mysql.default_socket setting.

(from http://php.net/manual/en/ref.pdo-mysql.connection.php)

Changing localhost to 127.0.0.1 will "force" the use of TCP.

Note: mysqli_connect is working fine with localhost.
