This patch will do a simple check to see if the last-modified value exists before doing checking against it. It also changes and documents the conditional logic so the "file" is altered if either information (last-modified or content-length) exists but is different than the original file.

Is there a chance that $remote['last-modified'] could legitimately be 0 (not necessarily intentionally, but perhaps due to server misconfiguration, etc) in which case isset() should be used in favor of empty()?

@elliotttf - It is not possible for last-modified to be legitimately zero since the spec requires an HTTP-date ( which cannot be zero.
