$phone_pattern = '/(?:\d\D*){10}/';

Please post the test data that you might be using with that code above, thanks.

Here is how to normalize a phone number.

When you post the test data I'll show you how to use this, based on the test data input that you've created.  Best regards, ~ray

@Kaufmed:
I do not know where to add this line you suggested:
$phone_pattern = '/(?:\d\D*){10}/';

You said, "how to change the pattern..." I assumed by that you meant change this line:

$phone_pattern = '/([0-9]{0,1})?[-.\s]?(\(?([0-9]{3})\)?[-.\s]?)?([0-9]{3})[-.\s]+([0-9]{4})([\s]?[x|ext]?[\s]?([0-9]+))?/s';

two 345678901: Equals what, exactly?  Is this a commonly expected client input?

Anyway, thanks for the points, ~Ray
