I don't think one should intentionally have long lines but, at the risk of offending many, I suggest that line length really isn't that important anymore.
Vim and emacs handle long lines pretty well, and they're installed on almost every Unix box. On Windows, you'll almost always be within a GUI text editor. I do think your $Stmt->bind_result style is the easiest to read, but if you just need to load a bunch of mostly static information in one statement, I have no problem with a 1000 character line.
