mssql_pconnect — Open persistent MS SQL connection
([ string $servername
[, string $username
[, string $password
[, bool $new_link
First, when connecting, the function would first try to find a
(persistent) link that's already open with the same host,
username and password. If one is found, an identifier for it
will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when
the execution of the script ends. Instead, the link will remain
open for future use (mssql_close() will not
close links established by mssql_pconnect()).
This type of links is therefore called 'persistent'.
The MS SQL server. It can also include a port number. e.g.
If a second call is made to mssql_pconnect() with
the same arguments, no new link will be established, but instead, the
link identifier of the already opened link will be returned. This
parameter modifies this behavior and makes
mssql_pconnect() always open a new link, even if
mssql_pconnect() was called before with the same
Returns a positive MS SQL persistent link identifier on success, or
FALSE on error.
