Hi, I ran into 32-bit problems, too, when working with >2GB files (in this case, raw DVD ISO images) on a 32-bit system (I couldn't find a reliable(!!) way to read a 4-byte absolute offset and seek to it). Of course, this warning is mentioned in the manpage, but really, not having at least a class for unsigned 32-bit ints (e.g. a Uint32 or a Uint64 for 64-bit platforms) which native functions like seek and friends coerce into a 32/64-bit uint makes PHP useless for anything that involves access to files or memory offsets (a problem from another project) > 2GB. >From a technical point of view: would such a UInt32 class actually be implementable, and at what cost to BC?
