IntlBreakIterator类

(PHP 5 >= 5.5.0, PHP 7)

“break迭代器”是一个ICU对象，它公开了在文本中定位边界（例如单词或句子边界）的方法。PHP IntlBreakIterator充当所有类型ICU中断迭代器的基类。如果有额外的功能可用，则intl扩展可以使用适当的子类（如IntlRuleBasedBreakIterator或IntlCodePointBreakIterator）公开ICU中断迭代器。

这个类实现可遍历。遍历IntlBreakIterator将生成表示文本边界连续位置的非负整数值，表示为从文本开头（位置为0）开始的UTF-8代码单位（字节）计数。迭代器产生的键只是自然数序列{0，1，2，…}。
