1. Internationalization and localization

Internationalization (i18n) is the process of designing software to support different languages ​​and regions. It involves making code and content agnostic to a specific language or culture.

Localization (l10n) is the process of adapting an international product to a specific language or region. It includes translating text, adjusting date format, currency, etc.

2. PHP Intl extension

PHP Intl extension provides powerful multi-language support. It contains functions for formatting and parsing dates, numbers, currencies, and other culturally relevant information. For example:

<?php
$date = new IntlDateFORMatter("en-US", IntlDateFormatter::FULL, IntlDateFormatter::FULL);
echo $date->format(time());
?>

3. Resource files

Resource files are containers that store translated text and culture-related information. PHP supports the use of multiple formats such as JSON, XML and PO. For example, a jsON resource file might contain the following:

{
"en-US": {
"title": "Welcome",
"content": "Welcome to our WEBsite!"
},
"es-ES": {
"title": "Bienvenido",
"content": "¡Bienvenido a nuestro sitio web!"
}
}

4. Load resource files

Use gettext() function to load resource files:

<?php
putenv("LC_ALL=en_US");
$locale = setlocale(LC_ALL, "en_US");
bindtextdomain("messages", "path/to/resources");
textdomain("messages");
?>

5. Translate text

gettext() Function is used to translate text:

<?php
echo gettext("Welcome to our website!");
?>

6. Set region and time zone

Use the setlocale() function to set the region and time zone:

<?php
setlocale(LC_ALL, "en_US");
?>

7. Date and time formatting

Format dates and times using the IntlDateFormatter and DateTime classes:

<?php
$date = new DateTime();
echo $date->format("Y-m-d H:i:s");
?>

8. Currency formatting

Use the NumberFormatter class to format currency:

<?php
$numberFormatter = new NumberFormatter("en_US", NumberFormatter::CURRENCY);
echo $numberFormatter->formatCurrency(1000, "USD");
?>

9. Debugging and Testing

Use setlocale() and gettext() functions to debug translation:

<?php
putenv("LC_ALL=es_ES");
echo gettext("Welcome to our website!");
?>
