PHP 正则表达式以提取电话号码

在这里，我正在尝试从电子邮件中提取电话号码

使用正则表达式

 ?('d|'+)('+|'d|'(|')|-| |'.){7,25} ?

但我想忽略在这些字符串中找到的匹配项

试试 http://rubular.com/r/b6K0LOcn3N任何更好的正则表达式???
对我的正则表达式的解释：?('d|'+)('+|'d|'(|')|-| |'.){7,25} ?

1. 开始捕获"否"。仅当检测到空格或未检测到空格时。
2. 如果第一个为 0-9 或 + 匹配 （+|''d|（|）| 中的任何字符，则开始匹配-| |.)
3. 7,25 因为电话号码的迷你长度是 7 和
4. 最多 25 个左右，包括空格和 - 等
