正则表达式：匹配从NNN开始并有10个号码的电话号码

Question

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 how to match numbers using PHP and regex?

Answer 1

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.
