msql_pconnect ( [string hostname] )
 
   msql_pconnect() acts very much like
   msql_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.
   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 (msql_close() will not close links 
   established by this function).
