I am working on implementing BreakIterator API [1]. I considered two
approaches: making a separate class or merging the API into the
existing TextIterator. Having a separate class would be a bit cleaner,
but I can see people wanting to use it in foreach(), and since
TextIterator already provides a lot of BreakIterator's functionality, I
decided that merging would be the best option. However, there is an
overlap between the BreakIterator API and the current TextIterator one,
so there will have to be some changes.
1. TextIterator::current() signature will change from:
mixed current()
to:
mixed current(integer &$offset)
in order to support BreakIterator's functionality of returning offset
in current().
2. TextIterator::next() will return the offset of the next boundary
instead of returning nothing.
3. TextIterator::rewind() will be renamed to TextIterator::first() to
conform to BreakIterator's first()/last() API.
So this is heads up. Let me know if you have a problem with this.
