How to validate a string which can contain numbers spaces, + and - using regex php

Question

I want to validate phone numbers like follows using php.

+009411774132482 011 2560-205

Answer 1

试试这个'/^\\+?[0-9 \\-]+$/'

Answer 2

This should do it...

preg_match('/^\+?[\d -]+\z/', $str);

CodePad .

It will allow...

• An optional preceding + .
• More than one of digits ( 0-9 ), space and - . If you want a minimum amount, swap the + with {9,} .
• Does not allow a trailing \\n .

Answer 3

试试这个正则表达式：

^[\d\s+-]+$
