README

A phone number library for PHP.

This library is a thin wrapper around giggsey/libphonenumber-for-php, itself a port of Google's libphonenumber.

It provides an equivalent functionality, with the following implementation differences:

• PhoneNumber is an immutable class; it can be safely passed around without having to worry about the risk for it to be changed;
• PhoneNumber is not just a mere data container, but provides all the methods to parse, format and validate phone numbers; it transparently encapsulates PhoneNumberUtil.

Installation

This library is installable via Composer:

composer require brick/phonenumber

Requirements

This library requires PHP 7.1 or later. for PHP 5.6 and PHP 7.0 support, use version 0.1.

Project status & release process

While this library is still under development, it is well tested and should be stable enough to use in production environments.

The current releases are numbered 0.x.y. When a non-breaking change is introduced (adding new methods, optimizing existing code, etc.), y is incremented.

When a breaking change is introduced, a new 0.x version cycle is always started.

It is therefore safe to lock your project to a given release cycle, such as 0.2.*.

If you need to upgrade to a newer release cycle, check the release history for a list of changes introduced by each further 0.x.0 version.

Quick start

All the classes lie in the Brick\PhoneNumber namespace.

To obtain an instance of PhoneNumber, use the parse() method:

• Using an international number: PhoneNumber::parse('+336123456789');
• Using a national number and a country code: PhoneNumber::parse('01 23 45 67 89', 'FR');

Validating a number

The parse() method is quite permissive with numbers; it basically attempts to match a country code, and validates the length of the phone number for this country.

If a number is really malformed, it throws a PhoneNumberParseException:

use Brick\PhoneNumber\PhoneNumber;
use Brick\PhoneNumber\PhoneNumberParseException;

try {
    $number = PhoneNumber::parse('+333');
}
catch (PhoneNumberParseException $e) {
    // 'The string supplied is too short to be a phone number.'
}

In most cases, it is recommended to perform an extra step of validation with isValidNumber() or isPossibleNumber():

if (! $number->isPossibleNumber()) {
    // a more lenient and faster check than `isValidNumber()`
}

if (! $number->isValidNumber()) {
    // strict check relying on up-to-date metadata library
}

As a rule of thumb, do the following:

• When the number comes from user input, do a full validation: parse() and catch PhoneNumberParseException, then call isValidNumber() (or isPossibleNumber() for a more lenient check) if no exception occurred;
• When the number is later retrieved from your database, and has been validated before, you can just perform a blind parse().

Formatting a number

Basic formatting

You can use format() with constants from the PhoneNumberFormat class:

$number = PhoneNumber::parse('+41446681800');
$number->format(PhoneNumberFormat::E164); // +41446681800
$number->format(PhoneNumberFormat::INTERNATIONAL); // +41 44 668 18 00
$number->format(PhoneNumberFormat::NATIONAL); // 044 668 18 00
$number->format(PhoneNumberFormat::RFC3966); // tel:+41-44-668-18-00

Formatting to call from another country

You may want to present a phone number to an audience in a specific country, with the correct international prefix when required. This is what formatForCallingFrom() does:

$number = PhoneNumber::parse('+447123456789');
$number->formatForCallingFrom('GB'); // 07123 456789
$number->formatForCallingFrom('FR'); // 00 44 7123 456789
$number->formatForCallingFrom('US'); // 011 44 7123 456789

Number types

In certain cases, it is possible to know the type of a phone number (fixed line, mobile phone, etc.), using the getNumberType() method, which returns a constant from the PhoneNumberType class:

PhoneNumber::parse('+336123456789')->getNumberType(); // PhoneNumberType::MOBILE
PhoneNumber::parse('+33123456789')->getNumberType(); // PhoneNumberType::FIXED_LINE

If the type is unknown, the PhoneNumberType::UNKNOWN value is returned. Check the PhoneNumberType class for all possible values.

Number information

You can extract the following information from a phone number:

$number = PhoneNumber::parse('+447123456789');
echo $number->getRegionCode(); // GB
echo $number->getCountryCode(); // 44
echo $number->getNationalNumber(); // 7123456789

Example numbers

You can get an example number for a country code and an optional number type (defaults to fixed line). This can be useful to use as a placeholder in an input field, for example:

echo PhoneNumber::getExampleNumber('FR'); // +33123456789
echo PhoneNumber::getExampleNumber('FR', PhoneNumberType::MOBILE); // +33612345678

The return type of getExampleNumber() is a PhoneNumber instance, so you can format it as you like:

echo PhoneNumber::getExampleNumber('FR')->formatForCallingFrom('FR'); // 01 23 45 67 89

If no example phone number is available for the country code / number type combination, a PhoneNumberException is thrown.
