Description
void 
ob_implicit_flush ( [int flag] )
     ob_implicit_flush() will turn implicit
     flushing on or off (if no flag is given,
     it defaults to on).  Implicit flushing will result in a flush
     operation after every output call, so that explicit calls to
     flush() will no longer be needed.
    
     See also flush(),
     ob_start(), and
     ob_end_flush().
