Regex: preg match() Help

I need to accept only 14 digits number

[a naguib 2000]

Hello,
How can I accept only 14 digits number with the leftmost digit not equal to zero (i.e from 10000000000000 to 99999999999999)?

My best trial was lacking condition of that the first number must not equal to zero:
preg_match("/\A\d{14}\z/",$no)

thanks

/[1-9]{1}\d{13}/ should do it.
