如何插入
每 115 个字符标记一次
如何每 115 个字符插入一个
我怎样才能做到这一点？
更好理解的是，第6阶段的评论部分是如何制作的。

我需要完全格式化的注释。
How can I insert a <br> tag every 115 characters? Which solution is better: strlen or regex?
How I can accomplish this?
Better to understand, how was made the comment section in stage6.

I need exactly the formatted comments.

这实在做不到。因为如果您天真地在 HTML 文档中每 115 个字符插入一个
我猜你的问题与控制网页的宽度有关，你最好使用 CSS 来控制文档的宽度。
This can't really be done. Because if you just naively insert a
<br>tag every 115 characters in the HTML document, you might end up within another tag, which would obviously not be what you wanted. You could use an HTML parser to parse the document, and only insert the<br>tag in places where text exists, but, I think that might be a little problematic, as you would have to account for inline elements, where you would want to put a<br>tag.I'm guessing your problem has something to do with controlling the width of your web page, and you would probably be better off using CSS to control the width of the document.
尽管注释表明这不是正确的使用方法（即，如果边界元素设置为正确换行，则不需要插入
只有当你处理文本，而不是原始 HTML，否则您可能会遇到 DOM 问题。小心行事。
编辑：如果您的目的是打破长单词以避免它们溢出边界框，您可以考虑在较长的单词中添加软连字符 (
) 实体。Although the comments suggest that this is not the correct approach to use (i.e. you shouldn't need to be inserting
<br />elements if the bounding element is set to wrap correctly), if you absolutely need to achieve something in PHP then wordrap() is probably the safest function for you:This should only be used if you're dealing with text, not with raw HTML, otherwise you might run into DOM issues. Tread carefully.
EDIT: if your intention is to break long words to avoid them overflowing your bounding box, you could consider adding soft hyphen (
) entities in the longer words.
