[clue-tech] I'm blind, or why is this PHP fwrite() failing?

I'd have guessed that perhaps fwrite returned something useful that 
wasn't true.

But this makes it look like the fwrite really is failing.

Is it possible some security setting is interferring?  The is_writable() 
call only looks at permissions so security (e.g., that prevents PHP from 
writing to a file it doesn't own) might be the culprit.

Looking through the PHP docs reaffirms my decision to avoid learning it 
at all costs.
