Re: 'the missing character'

I don't understand xcount(). Instead of xcount(), why not use strlen()? Say we have 7100 chars.... If you step through, first pass $i = 0 $chunk_count = 2 $start = 0 $final = 3500 $text[] is chars 0-3499 second pass $i = 1 // from $i++ $chunk_count = 2 $start = 3501 // problem is here - note the endpoint of the last pass in $text[]? $final = 3499 $text[] is chars 3501-7000 // what happened to char 3500 itself? Remember that substr() takes a start point, and an offset - not an endpoint. So after the first pass, you've read in 0-3499 as is correct, but you have an extraneous if() clause that inc's your start by one, and then adds 3500. Drop the second if($start == 0) clause which sets $start to 1.
