    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,…}。

    IntlBreakIterator implements Traversable
