isNumberGeographical() public method

Tests whether a phone number has a geographical association. It checks if the number is associated to a certain region in the country where it belongs to. Note that this doesn't verify if the number is actually in use. isNumberGeographical(PhoneNumberType, $countryCallingCode) Tests whether a phone number has a geographical association, as represented by its type and the country it belongs to. This version exists since calculating the phone number type is expensive; if we have already done this, we don't want to do it again.
public isNumberGeographical ( PhoneNumber | integer $phoneNumberObjOrType, integer | null $countryCallingCode = null ) : boolean
$phoneNumberObjOrType PhoneNumber | integer A PhoneNumber object, or a PhoneNumberType integer
$countryCallingCode integer | null Used when passing a PhoneNumberType
return boolean
