getCountryMobileToken() public static méthode

Returns the mobile token for the provided country calling code if it has one, otherwise returns an empty string. A mobile token is a number inserted before the area code when dialing a mobile number from that country from abroad.
public static getCountryMobileToken ( integer $countryCallingCode ) : string
$countryCallingCode integer the country calling code for which we want the mobile token
Résultat string the mobile token, as a string, for the given country calling code
 /**
  * Returns a text description for the given phone number, in the language provided. The
  * description might consist of the name of the country where the phone number is from, or the
  * name of the geographical area the phone number is from if more detailed information is
  * available.
  *
  * <p>This method assumes the validity of the number passed in has already been checked, and that
  * the number is suitable for geocoding. We consider fixed-line and mobile numbers possible
  * candidates for geocoding.
  *
  * <p>If $userRegion is set, we also consider the region of the user. If the phone number is from
  * the same region as the user, only a lower-level description will be returned, if one exists.
  * Otherwise, the phone number's region will be returned, with optionally some more detailed
  * information.
  *
  * <p>For example, for a user from the region "US" (United States), we would show "Mountain View,
  * CA" for a particular number, omitting the United States from the description. For a user from
  * the United Kingdom (region "GB"), for the same number we may show "Mountain View, CA, United
  * States" or even just "United States".
  *
  * @param PhoneNumber $number a valid phone number for which we want to get a text description
  * @param string $locale the language code for which the description should be written
  * @param string $userRegion the region code for a given user. This region will be omitted from the
  *     description if the phone number comes from this region. It is a two-letter uppercase ISO
  *     country code as defined by ISO 3166-1.
  * @return string a text description for the given language code for the given phone number
