Turn display_errors on and off

I would like to be able to turn on-screen errors on and off selectively within scripts. I have tried using the error_reporting() function but this stops error messages going to the log file, which I want always to happen. It seems to me that I want to set the display_errors configuration option within my scripts. Is this possible, or is there an other way to do what I want?
