Also, I'd advise against ever using the three parameter form of open when wanting read mode. It's much better to just let read mode be assumed so you don't risk putting the symbol in the wrong direction and overwriting your file.

And risk having the second arg contain something scary?
$file = '> somefile';

    That's a fair point, although I'm not sure I would qualify that as "scary".

    Given most of the file operations I perform are ones where I'm specifying the filename passed in the variable, I don't see this as a big risk. However, if there was ever a point where the file was specified in by the user and not validated in any way, then doing the three parameter form of read mode would be wise.

    For me at least, the right of being lazy is going to win out for this small risk otherwise. I find mistyping to be a bigger worry then intentional mischief.
