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.
