ifx_pconnect -- Open persistent Informix connection
Description
int 
ifx_pconnect ( [string database [, string userid [, string password]]] )
 
     Returns: A positive Informix persistent link identifier on success,
     or FALSE on error
    
     ifx_pconnect() acts very much like
     ifx_connect() with two major differences.
    
 
     This function behaves exactly like ifx_connect()
     when PHP is not running as an Apache module.
     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 (ifx_close() will not
     close links established by ifx_pconnect()).
    
 
     This type of links is therefore called 'persistent'.
