Re: Saving an array as a file

I may not be understanding exactly what you're looking to do. You have an array that you want to save to disk, right? Is it for storage only, or does it need to be readable/parseable by a person or another process? If it's for storage only, use serialize/unserialize $x = serialize($arrayname); echo $x; // neat bunch of stuff here $arrayname = unserialize($x); Does this help at all?
