怎么判断一段数字是不是电话号码？How does it decide a number is a phone number?

提取去掉符号后共有 7–15 位数字的序列（符合国际电话号码长度），允许 +、空格、短横线、小圆点和括号；少于 7 位（如 6 位短号、ID）或多于 15 位的会被忽略，形如 2026-10-17 的日期也会跳过。It extracts sequences that have 7 to 15 digits once symbols are removed (the length range of international phone numbers), allowing +, spaces, dashes, dots and brackets. Anything shorter (6-digit codes, IDs) or longer than 15 digits is ignored, and dates like 2026-10-17 are skipped.

“统一为纯数字格式”做什么？What does Normalise to digits only do?

它去掉所有空格和符号，只保留数字，并在原本带 + 的号码前保留 +，例如 +1 (415) 555-0132 变成 +14155550132，方便存入数据库或按 E.164 比较。It strips every space and symbol, keeping only the digits, and preserves a leading + if the original had one — so +1 (415) 555-0132 becomes +14155550132, handy for storing in a database or comparing in E.164 form.

会不会漏掉或误判？Can it miss numbers or get them wrong?

这是基于格式的启发式提取，不验证号码是否真实存在或归属哪个国家。没有分隔符的长数字串（如订单号）可能被当成号码，而写法很特别的号码可能被漏掉；提取后请人工核对。It is a format-based heuristic and does not verify that a number really exists or which country it belongs to. Long unseparated digit strings (such as order numbers) may be picked up, and unusually formatted numbers may be missed, so review the results.
