Brief Overview

The simple-php-translation is a simple solution for adding translations to your PHP apps.

Install:

composer require diversen/simple-php-translation

If you want to use google auto translate, require the following:

composer require google/cloud-translate

Translations are placed in files named:

lang/en/language.php
lang/da/language.php

E.g. inside your app test_app

test_app/lang/en/language.php

The language.php file could consist of this:

$LANG = array ();
$LANG['Welcome to my blog'] = 'Welcome to my blog';

A Danish translation could be found in:

test_app/lang/da/language.php

And this language.php could consist of:

    $LANG = array ();
    $LANG['Welcome to my blog'] = 'Velkommen til min blog';

Load language

use Diversen\Lang;

$l = new Lang();

// Most often all translations are placed in a single folder
$l->setSingleDir("test_app");

// But you can also set dirs, and look for language files inside multiple language dirs:
// $l->setDirsInsideDir("modules/");

// load language. E.g. danish ('da')
// $l->loadLanguage('da');

// Or english
// e.g. test_app/lang/da/language.php
$l->loadLanguage('en');

// now all language files are loaded, and we can translate

Translate

// simple

use Diversen\Lang;

echo Lang::translate('Here is a text');

// with substitution and a span to indicate that a part of a string should not be translated

echo Lang::translate('User with ID <span class="notranslate">{ID}</span> has been locked!', array ('ID' => $id))

Extract strings

This will extract all Lang::translate calls, and add new values to translation files.

use Diversen\Translate\Extractor;

// same pattern as above for extraction

$e = new Extractor();
$e->defaultLanguage ='en'; // which language will we extract to

// Most often you will just use a single dir. Like this
$e->setSingleDir("test_app");

// Set multiple dirs, like this:
// This will create translation folders in e.g. modules/blog, modules/account
// $e->setDirsInsideDir('modules/');

$e->updateLang();

The $e->updateLang() call only add new strings found in the source, and remove strings that are removed from the source. It also knows if you have changed the value of a translation key, then it will leave the value as it is. It only updates the translation files, when a new key value is found.

Auto translate using google translate API

You will need to setup google cloud translation:

https://cloud.google.com/translate/docs/basic/setup-basic

Then require the composer package google/cloud-translate

composer require google/cloud-translate

Remember to export the GOOGLE_APPLICATION_CREDENTIALS or you will not be able to run the script.

// same pattern as above for google auto translation.
use Diversen\Translate\GoogleTranslate;

include_once "vendor/autoload.php";

// Google translator needs this. Substitue with path to your own .json file  
putenv("GOOGLE_APPLICATION_CREDENTIALS=config-locale/pebble-2c949028ebcc.json");

$t = new GoogleTranslate();
$t->target = 'da'; // danish
$t->source = 'en';

$t->setSingleDir("app");

// Or set multiple dirs like this:
// This will create translation folders in e.g. modules/blog, modules/account
// $e->setDirsInsideDir('modules/');

$t->updateLang();

Demo

Inside the test_app/ directory, there is a small php app consisting of one PHP file: test_app/index.php. There is also included javascript in this file. The javascript Lang.translate method will also be extracted when using the Extractor class.

The Javascript file test_app/js/lang.js will do the translation.

Start the app:

php -S localhost:8000 -t test_app

Visit http://localhost:8000

You can also test the danish translation at:

http://localhost:8000?lang=da

I there is no translations then any string will get the "NT: " (Not Translated) prefix.

You can test this by removing the en language file directory:

rm -rf test_app/lang/en

Extract the english translation en using the script test/extract.php.

php test/extract.php

Reload the browser.

Now all translation are loaded from a file and the prefix 'NT: ' is removed.

There is also a small script for translating into danish (da). test/google_translate.php

In order to use this script, you will need to setup a google service account. Then change this part of the script:

putenv("GOOGLE_APPLICATION_CREDENTIALS=google_json/pebble-2c949028ebcc.json");

To:

putenv("GOOGLE_APPLICATION_CREDENTIALS=path/to/service-account-your-key.json");

Now you can run:

php test/google_translate.php

The translation will look like this: test_app/lang/da/language.php

Finally there is test/to_js.php script which translates into js module exports, which then can be loaded and translated by the EMS module test_app/js/lang.js
