# The IntlPartsIterator class

(PHP 5 >= 5.5.0, PHP 7)

## Introduction

Objects of this class can be obtained from IntlBreakIterator objects. While the break iterators provide a sequence of boundary positions when iterated, IntlPartsIterator objects provide, as a convenience, the text fragments comprehended between two successive boundaries.

The keys may represent the offset of the left boundary, right boundary, or they may just the sequence of non-negative integers. See IntlBreakIterator::getPartsIterator().
