Installation
|
||||
------------
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
You can install the component in two different ways:
|
||||
|
||||
* Using the official Git repository (https://github.com/symfony/Intl);
|
||||
* [Install it via Composer] [0] (`symfony/intl` on [Packagist] [1]).
|
||||
|
||||
If you install the component via Composer, the following classes and functions
|
||||
of the intl extension will be automatically provided if the intl extension is
|
||||
not loaded:
|
||||
|
||||
* [`\Locale`] [2]
|
||||
* [`\NumberFormatter`] [3]
|
||||
* [`\IntlDateFormatter`] [4]
|
||||
* [`\Collator`] [5]
|
||||
* [`intl_is_failure()`] [6]
|
||||
* [`intl_get_error_code()`] [7]
|
||||
* [`intl_get_error_message()`] [8]
|
||||
* [`intl_error_name()`] [9]
|
||||
|
||||
If you don't use Composer but the Symfony ClassLoader component, you need to
|
||||
load them manually by adding the following lines to your autoload code:
|
||||
|
||||
if (!function_exists('intl_is_failure')) {
|
||||
require '/path/to/Icu/Resources/stubs/functions.php';
|
||||
|
||||
$loader->registerPrefixFallback('/path/to/Icu/Resources/stubs');
|
||||
}
|
||||
|
||||
Stubbed Classes
|
||||
---------------
|
||||
|
||||
The stubbed classes of the intl extension are limited to the locale "en" and
|
||||
will throw an exception if you try to use a different locale. For using other
|
||||
locales, [install the intl extension] [10] instead.

|
||||
### ResourceBundle
|
||||
|
||||
The `\ResourceBundle` class is not and will not be supported. Instead, this
|
||||
component ships a set of readers and writers for reading and writing arrays
|
||||
(or array-like objects) from/to resource bundle files. The following classes
|
||||
are supported:
|
||||
|
||||
##### TextBundleWriter
|
||||
|
||||
Writes an array or an array-like object to a plain text resource bundle. The
|
||||
resulting .txt file can be converted to a binary .res file with the
|
||||
`BundleCompiler` class.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Writer\TextBundleWriter;
|
||||
use Symfony\Component\Intl\ResourceBundle\Compiler\BundleCompiler;
|
||||
|
||||
$writer = new TextBundleWriter();
|
||||
$writer->write('/path/to/bundle', 'en', array(
|
||||
'Data' => array(
|
||||
'entry1',
|
||||
'entry2',
|
||||
...
|
||||
),
|
||||
));
|
||||
|
||||
$compiler = new BundleCompiler();
|
||||
$compiler->compile('/path/to/bundle', '/path/to/binary/bundle');
|
||||
|
||||
The command "genrb" must be available for the `BundleCompiler` to work. If the
|
||||
command is located in a non-standard location, you can pass its path to the
|
||||
`BundleCompiler` constructor.
|
||||
|
||||
##### PhpBundleWriter
|
||||
|
||||
Writes an array or an array-like object to a .php resource bundle.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Writer\PhpBundleWriter;
|
||||
|
||||
$writer = new PhpBundleWriter();
|
||||
$writer->write('/path/to/bundle', 'en', array(
|
||||
'Data' => array(
|
||||
'entry1',
|
||||
'entry2',
|
||||
...
|
||||
),
|
||||
));
|
||||
|
||||
##### BinaryBundleReader
|
||||
|
||||
Reads binary resource bundle files and returns an array or an array-like object.
|
||||
This class currently only works with the intl extension installed.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\BinaryBundleReader;
|
||||
|
||||
$reader = new BinaryBundleReader();
|
||||
$data = $reader->read('/path/to/bundle', 'en');
|
||||
|
||||
echo $data['Data']['entry1'];
|
||||
|
||||
##### PhpBundleReader
|
||||
|
||||
Reads resource bundles from .php files and returns an array or an array-like
|
||||
object.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\PhpBundleReader;
|
||||
|
||||
$reader = new PhpBundleReader();
|
||||
$data = $reader->read('/path/to/bundle', 'en');
|
||||
|
||||
echo $data['Data']['entry1'];
|
||||
|
||||
##### BufferedBundleReader
|
||||
|
||||
Wraps another reader, but keeps the last N reads in a buffer, where N is a
|
||||
buffer size passed to the constructor.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\BinaryBundleReader;
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\BufferedBundleReader;
|
||||
|
||||
$reader = new BufferedBundleReader(new BinaryBundleReader(), 10);
|
||||
|
||||
// actually reads the file
|
||||
$data = $reader->read('/path/to/bundle', 'en');
|
||||
|
||||
// returns data from the buffer
|
||||
$data = $reader->read('/path/to/bundle', 'en');
|
||||
|
||||
// actually reads the file
|
||||
$data = $reader->read('/path/to/bundle', 'fr');
|
||||
|
||||
##### StructuredBundleReader
|
||||
|
||||
Wraps another reader and offers a `readEntry()` method for reading an entry
|
||||
of the resource bundle without having to worry whether array keys are set or
|
||||
not. If a path cannot be resolved, `null` is returned.
|
||||
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\BinaryBundleReader;
|
||||
use Symfony\Component\Intl\ResourceBundle\Reader\StructuredBundleReader;
|
||||
|
||||
$reader = new StructuredBundleReader(new BinaryBundleReader());
|
||||
|
||||
$data = $reader->read('/path/to/bundle', 'en');
|
||||
|
||||
// Produces an error if the key "Data" does not exist
|
||||
echo $data['Data']['entry1'];
|
||||
|
||||
// Returns null if the key "Data" does not exist
|
||||
echo $reader->readEntry('/path/to/bundle', 'en', array('Data', 'entry1'));
|
||||
|
||||
Additionally, the `readEntry()` method resolves fallback locales. For example,
|
||||
the fallback locale of "en_GB" is "en". For single-valued entries (strings,
|
||||
numbers etc.), the entry will be read from the fallback locale if it cannot be
|
||||
found in the more specific locale. For multi-valued entries (arrays), the
|
||||
values of the more specific and the fallback locale will be merged. In order
|
||||
to suppress this behavior, the last parameter `$fallback` can be set to `false`.
|
||||
|
||||
echo $reader->readEntry('/path/to/bundle', 'en', array('Data', 'entry1'), false);
|
||||
|
||||
Included Resource Bundles
|
||||
-------------------------
|
||||
|
||||
The ICU data is located in several "resource bundles". You can access a PHP
|
||||
wrapper of these bundles through the static `Intl` class.
|
||||
|
||||
Languages and Scripts
|
||||
~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The translations of language and script names can be found in the language
|
||||
bundle.
|
||||
|
||||
use Symfony\Component\Intl\Intl;
|
||||
|
||||
\Locale::setDefault('en');
|
||||
|
||||
$languages = Intl::getLanguageBundle()->getLanguageNames();
|
||||
// => array('ab' => 'Abkhazian', ...)
|
||||
|
||||
$language = Intl::getLanguageBundle()->getLanguageName('de');
|
||||
// => 'German'
|
||||
|
||||
$language = Intl::getLanguageBundle()->getLanguageName('de', 'AT');
|
||||
// => 'Austrian German'
|
||||
|
||||
$scripts = Intl::getLanguageBundle()->getScriptNames();
|
||||
// => array('Arab' => 'Arabic', ...)
|
||||
|
||||
$script = Intl::getLanguageBundle()->getScriptName('Hans');
|
||||
// => 'Simplified'
|
||||
|
||||
All methods accept the translation locale as last, optional parameter, which
|
||||
defaults to the current default locale.
|
||||
|
||||
$languages = Intl::getLanguageBundle()->getLanguageNames('de');
|
||||
// => array('ab' => 'Abchasisch', ...)
|
||||
|
||||
Countries
|
||||
~~~~~~~~~
|
||||
|
||||
The translations of country names can be found in the region bundle.
|
||||
|
||||
use Symfony\Component\Intl\Intl;
|
||||
|
||||
\Locale::setDefault('en');
|
||||
|
||||
$countries = Intl::getRegionBundle()->getCountryNames();
|
||||
// => array('AF' => 'Afghanistan', ...)
|
||||
|
||||
$country = Intl::getRegionBundle()->getCountryName('GB');
|
||||
// => 'United Kingdom'
|
||||
|
||||
All methods accept the translation locale as last, optional parameter, which
|
||||
defaults to the current default locale.
|
||||
|
||||
$countries = Intl::getRegionBundle()->getCountryNames('de');
|
||||
// => array('AF' => 'Afghanistan', ...)
|
||||
|
||||
Locales
|
||||
~~~~~~~
|
||||
|
||||
The translations of locale names can be found in the locale bundle.
|
||||
|
||||
use Symfony\Component\Intl\Intl;
|
||||
|
||||
\Locale::setDefault('en');
|
||||
|
||||
$locales = Intl::getLocaleBundle()->getLocaleNames();
|
||||
// => array('af' => 'Afrikaans', ...)
|
||||
|
||||
$locale = Intl::getLocaleBundle()->getLocaleName('zh_Hans_MO');
|
||||
// => 'Chinese (Simplified, Macau SAR China)'
|
||||
|
||||
All methods accept the translation locale as last, optional parameter, which
|
||||
defaults to the current default locale.
|
||||
|
||||
$locales = Intl::getLocaleBundle()->getLocaleNames('de');
|
||||
// => array('af' => 'Afrikaans', ...)
|
||||
|
||||
Currencies
|
||||
~~~~~~~~~~
|
||||
|
||||
The translations of currency names and other currency-related information can
|
||||
be found in the currency bundle.
|
||||
|
||||
use Symfony\Component\Intl\Intl;
|
||||
|
||||
\Locale::setDefault('en');
|
||||
|
||||
$currencies = Intl::getCurrencyBundle()->getCurrencyNames();
|
||||
// => array('AFN' => 'Afghan Afghani', ...)
|
||||
|
||||
$currency = Intl::getCurrencyBundle()->getCurrencyName('INR');
|
||||
// => 'Indian Rupee'
|
||||
|
||||
$symbol = Intl::getCurrencyBundle()->getCurrencySymbol('INR');
|
||||
// => '₹'
|
||||
|
||||
$fractionDigits = Intl::getCurrencyBundle()->getFractionDigits('INR');
|
||||
// => 2
|
||||
|
||||
$roundingIncrement = Intl::getCurrencyBundle()->getRoundingIncrement('INR');
|
||||
// => 0
|
||||
|
||||
All methods (except for `getFractionDigits()` and `getRoundingIncrement()`)
|
||||
accept the translation locale as last, optional parameter, which defaults to the
|
||||
current default locale.
|
||||
|
||||
$currencies = Intl::getCurrencyBundle()->getCurrencyNames('de');
|
||||
// => array('AFN' => 'Afghanische Afghani', ...)
