ShortNumberInfo

Getting Started

As with PhoneNumberUtil, ShortNumberInfo uses a singleton.

$shortNumberUtil = \libphonenumber\ShortNumberInfo::getInstance();

Example Numbers

getExampleShortNumber()

Returns an example short phone number for the $regionCode supplied

var_dump($shortNumberUtil->getExampleShortNumber('GB'));
// string(3) "150"

getExampleShortNumberForCost()

Returns a valid short number for the specified $regionCode and $cost category.

var_dump($shortNumberUtil->getExampleShortNumberForCost('GB', \libphonenumber\ShortNumberCost::TOLL_FREE));
// string(6) "116000"

var_dump($shortNumberUtil->getExampleShortNumberForCost('GB', \libphonenumber\ShortNumberCost::PREMIUM_RATE));
// string(0) ""

var_dump($shortNumberUtil->getExampleShortNumberForCost('US', \libphonenumber\ShortNumberCost::PREMIUM_RATE));
// string(5) "24280"

Emergency Numbers

isEmergencyNumber()

Returns whether the supplied $number exactly matches an emergency service number for the $region.

var_dump($shortNumberUtil->isEmergencyNumber('999', 'GB'));
// bool(true)

var_dump($shortNumberUtil->isEmergencyNumber('9999', 'GB'));
// bool(false)

connectsToEmergencyNumber()

Checks whether the $number (when dialled) might connect to an emergency service within the given $region.

var_dump($shortNumberUtil->connectsToEmergencyNumber('999', 'GB'));
// bool(true)

// Note, 999 is a GB emergency service, but additional digits after the 999
// might be possible to dial.
var_dump($shortNumberUtil->connectsToEmergencyNumber('999123', 'GB'));
// bool(true)

Short Number Validation

isPossibleShortNumber()

Checks whether the specified PhoneNumber object is a possible short number.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->isPossibleShortNumber($phoneNumber));
// bool(true)

isPossibleShortNumberForRegion()

Checks whether the supplied $shortNumber (which can either be a string or a PhoneNumber object) is possible for the $region.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->isPossibleShortNumberForRegion($phoneNumber, 'GB'));
// bool(true)

var_dump($shortNumberUtil->isPossibleShortNumberForRegion('1234', 'GB'));
// bool(true)

isValidShortNumber()

Checks whether the specified PhoneNumber object is a valid short number.

Important: This doesn't actually validate whether the number is in use. libphonenumber-for-php is only able to validate number patterns, and isn't able to check with telecommunication providers.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->isValidShortNumber($phoneNumber));
// bool(true)

isValidShortNumberForRegion()

Checks whether the supplied $shortNumber (which can either be a string or a PhoneNumber object) is valid for the $region.

Important: As with isValidShortNumber(), this can not validate whether the number is actually in use.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->isValidShortNumberForRegion($phoneNumber, 'GB'));
// bool(true)

var_dump($shortNumberUtil->isValidShortNumberForRegion('1234', 'GB'));
// bool(false)

isCarrierSpecific()

Returns whether the supplied PhoneNumber is a carrier specific short number.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(1);
$phoneNumber->setNationalNumber('611');

var_dump($shortNumberUtil->isCarrierSpecific($phoneNumber));
// (bool) true

isCarrierSpecificForRegion()

Returns whether the supplied PhoneNumber is a carrier specific short number in the $region provided.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(1);
$phoneNumber->setNationalNumber('611');

var_dump($shortNumberUtil->isCarrierSpecificForRegion($phoneNumber, 'US'));
// (bool) true

Expected Costs

getExpectedCost()

Returns the expected cost (as a ShortNumberCost constant) of the supplied PhoneNumber short number.

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->getExpectedCost($phoneNumber, 'GB'));
// int(10) (\libphonenumber\ShortNumberCost::UNKNOWN_COST)

getExpectedCostForRegion()

Returns the expected cost (as a ShortNumberCost constant) of the supplied $number (which can be a string or a PhoneNumber object).

$phoneNumber = new \libphonenumber\PhoneNumber();
$phoneNumber->setCountryCode(44);
$phoneNumber->setNationalNumber('118118');

var_dump($shortNumberUtil->getExpectedCostForRegion($phoneNumber, 'GB'));
// int(10) (\libphonenumber\ShortNumberCost::UNKNOWN_COST)

var_dump($shortNumberUtil->getExpectedCostForRegion('24280', 'US'));
// int(4) (\libphonenumber\ShortNumberCost::PREMIUM_RATE)
