fbsql_pconnect ( [string hostname [, string username [, string password]]] )
 
     Returns: A positive FrontBase persistent link identifier on
     success, or FALSE on error.
    
     fbsql_pconnect() establishes a connection
     to a FrontBase server.  The following defaults are assumed for
     missing optional parameters: host =
     'localhost', username = "_SYSTEM"
     and password = empty password.
    
     To set Frontbase server port number, use
     fbsql_select_db().
    
     fbsql_pconnect() acts very much like
     fbsql_connect() with two major differences.
    
 
     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.
    
 
     This type of links is therefore called 'persistent'.
