Regex that allows mobile numbers starting with * or #

I need a regex that matches a mobile phone number(with a maximum of 9 digits) starting with * or # , like these ones:

#964418878
*8745858
*98568开发者_运维技巧6869 

Hope you can help me out

The following should do what you want:

/^[*#]\d{1,9}$/

This assume your strings ONLY consist of the phone numbers, one per string. If you're just checking that they exist in a larger string, remove the ^ and $ characters.

Just nine consecutive digits?

^(\*|#)\d{1,9}$

Replace 1 with the minimum number of digits you want to have.

This is a good place to start learning regular expressions: http://www.regular-expressions.info/

Something like this, depending on the regex flavor:

/[#*]?\d{1,9}/

\d is an alias for [0-9], so if the former isn't supported on your platform (is there such a beast?) then use the latter. Also, this is the syntax for a find, if you want a match, add ^ and $ to beginning and end, respectively.
