Ah, now I see. If you want to make up a difficult problem, that's swell. Throw in the additional requirement that there are so many records that there isn't enough "RAM + swap" to contain all the record offsets. Add an architectural requirement that it support bytes of infinite and variable length if that makes it more fun. PHP has access to the same stream-io routines in stdlib that a C application would use. I have little interest in unsolvable theoretical problems when so many practical problems remain poorly solved.
