PHP PhoneNumber::clearPreferredDomesticCarrierCode方法代码示例

 /**
  * Takes two phone numbers and compares them for equality.
  *
  * <p>Returns EXACT_MATCH if the country_code, NSN, presence of a leading zero
  * for Italian numbers and any extension present are the same. Returns NSN_MATCH
  * if either or both has no region specified, and the NSNs and extensions are
  * the same. Returns SHORT_NSN_MATCH if either or both has no region specified,
  * or the region specified is the same, and one NSN could be a shorter version
  * of the other number. This includes the case where one has an extension
  * specified, and the other does not. Returns NO_MATCH otherwise. For example,
  * the numbers +1 345 657 1234 and 657 1234 are a SHORT_NSN_MATCH. The numbers
  * +1 345 657 1234 and 345 657 are a NO_MATCH.
  *
  * @param $firstNumberIn PhoneNumber|string First number to compare. If it is a
  * string it can contain formatting, and can have country calling code specified
  * with + at the start.
  * @param $secondNumberIn PhoneNumber|string Second number to compare. If it is a
  * string it can contain formatting, and can have country calling code specified
  * with + at the start.
  * @throws \InvalidArgumentException
  * @return int {MatchType} NOT_A_NUMBER, NO_MATCH,
