Класс IntlBreakIterator

Введение

Итератор прерывания (Break iterator) - это объект ICU предоставляющий методы для определения границ в тексте (например границы слова или предложения). В PHP класс IntlBreakIterator служит базовым классом для всех типов итераторов прерывания ICU. Есть и дополнительная функциональность, расширение intl может расширять этот класс подходящими подклассами, такими как IntlRuleBasedBreakIterator или IntlCodePointBreakIterator.

Этот класс реализует интерфейс Traversable. Traversing an Итерация IntlBreakIterator порождает неотрицательные целые значения, представляющие из себя успешное нахождение границ в тексте, и равные позиции найденного символа UTF-8 отсчитанной от начала текста (позиция первого символа равна 0). Ключи возвращенных значений представляют из себя последовательность натуральных чисел {0, 1, 2, …}.
