Regex : Matching phone numbers starting with NNN and having 10 numbers

I need to match phone numbers that :

• start with 010 or 012 or 016 or 019

• Consist of 10 numbers exactly

Can you please help me on h开发者_开发知识库ow to match numbers using PHP and regex?

---

return preg_match('/^01[0269]\\d{7}$/', $theStringToTest);

This will match 0, 1, one of (0, 2, 6, 9), and then any 7 numbers (3+7==10). The ^ means start of string and $ means end of string.

---

I think I'd use ^01[0269][0-9]{7}$

Use this Regex

/\b(010|012|016|019)[0-9]{7}\b/g
