Numbers and Spaces - Loose Phone Regex

How do I test whether a string contains only numbers and spaces using RegEx?

i.e.

1. 021 123 4567 is valid
2. 0211234567 is valid
3. 0211 234 567 is valid

Pretty loose, but this meets my requirements.

Suggestions?

How about /^[\d ]+$/? If it needs to start and end with a digit, /^\d[\d ]*\d$/ should do it.

• [0-9] <-- this means any single digit between 0 and 9
• [0-9 ] <-- this means any single digit between 0 and 9, or a space
• [0-9 ]{1,} <-- this means any single digit between 0 and 9, or a space, 1 or more times
• [0-9 ]{1,9} <-- this means any single digit between 0 and 9, or a space, 1 to 9 times

n of digits with any number of spaces:

^(\s*\d\s*){11}$

here n=11; Test: here

Something like:

\d*|\s+^[A-Za-z]
