i also think better is without @. On production server there will be 
displayErrors set to 0.

I think one reason for using the @ was a problem in former php versions 
with file_exists, where a warning was thrown if file wasn't existent, 
and @ was the only way to supress. But this is fixed in php 5.

I also read in performance tips that the @ costs a lot of time too.
