对于你的问题，这个正则表达式会做：

For you question this regex will do:

^[0-9\+\- \(\)]{10,25}

但是！要检查电话号码肯定不好，因为它允许加号出现在任何地方，允许未闭合的括号...

因此，如果你想检查电话号码，你可以将它分成两个。一个用于正则表达式以检查输入中是否存在无效字符，另一个用于检查语法...

But! To check phone number it definitely not good, as it allows the plus sign to appear anywhere, allows unclosed parentheses...
So if you want to check phone numbers you may split it to two. One for a regex to check that no invalid char are in the input, and one other to check syntax...
