Returns: A positive MS SQL link identifier on success, or
FALSE on error.
mssql_connect() establishes a
connection to a MS SQL server. The servername argument has to
be a valid servername that is defined in the 'interfaces'
file.
In case a second call is made to
mssql_connect() with the same arguments, no new link will
be established, but instead, the link identifier of the
already opened link will be returned.
The link to the server will be closed as soon as the
execution of the script ends, unless it's closed earlier by
explicitly calling mssql_close().

mssql_close().
