sybase_pconnect ( [string servername [, string username [, string password [, string charset [, string appname]]]]] )
 
   Returns a positive Sybase persistent link identifier on success,
   or FALSE on error.
  
   sybase_pconnect() acts very much like
   sybase_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 (sybase_close() will not
   close links established by sybase_pconnect()).
  
 
   This type of links is therefore called 'persistent'.
