Regular expression for a mobile number

Question

I want to write a regular expression for a mobile number

1. The field should not be empty
2. Should be minimum of 10 - 15 char
3. The field should contain only number eg : 9042248903

I tried using the below expression

^\d+([\.\,][0]{2})?$
^[0-9]+$

Answer 1

Those specifications can be met with

^[0-9]{10,15}$

The start and end markers ^$ ensure there's nothing on either side.

[0-9] gives you a digit.

{10,15} meannse ten to fifteen occurrences of that digit speciffication.
