translate a PHP $string using google translator API

问题

been google'ing for a while how is the best way to translate with google translator in PHP, found very different ways converting URLS, or using Js but i want to do it only with php (or with a very simple solution JS/JQUery)

example:

//hopefully with $from_lan and $to_lan being like 'en','de', .. or similar
function translate($from_lan, $to_lan, $text){

// do

return $translated_text;

}

can you give me a clue? or maybe you already have this function..

my intention it's to use it only for the languages i have not already defined (or keys i haven't defined), that's why i wan it so simple, will be only temporal..

EDIT

thanks for your replies we are now trying this soulutions:

function auto_translate($from_lan, $to_lan, $text){
// do


$json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan));
$translated_text = $json->responseData->translatedText;


return $translated_text;

}

(there was a extra 'g' on variables for lang... anyway)

it returns: works now :)

i don't really understand much the function, so any idea why is not acepting the object? (now i do)

OR:

    function auto_translate($from_lan, $to_lan, $text){
    // do

//    $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan));
//    $translated_text = $json['responseData']['translatedText'];
    error_reporting(1);
    require_once('GTranslate.php');
    try{
       $gt = new Gtranslate();
       $translated_text = $gt->english_to_german($text);

     } catch (GTranslateException $ge)
     {
           $translated_text= $ge->getMessage();
     }


    return $translated_text;
}

And this one looks great but it doesn't even gives me an error, the page won't load (error_report(1) :S)

thanks in advance!

I haven't tested this yet, but try:

function translate($from_lan, $to_lan, $text){
    $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan));
    $translated_text = $json->responseData->translatedText;

    return $translated_text;
}

EDIT: Fixed, tested and works.

I have new solution for this.. Because last solution need new version and some fetched other issue.

---

    $text = 'Test new message only.';
    $apiKey = '<past your google api key here>';
    $url = 'https://www.googleapis.com/language/translate/v2?key=' . $apiKey . '&q=' . rawurlencode($text) . '&source=en&target=fr';
    $handle = curl_init($url);
    curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($handle);
    $responseDecoded = json_decode($response, true);

    curl_close($handle);

    print_r($responseDecoded['data']['translations'][0]['translatedText']);
    die;

    //expected output
     Testez le nouveau message uniquement.

I hope is very helpful in PHP

Want to use Google Translate API in PHP, you would need to insert "google/cloud-translate" and "google/apiclient" in your composer file, run composer update and call translate method after creating an object of the following class:

<?php

require_once APP_ROOT . '/library/google-api-php-client/src/Google_Client.php';
require_once APP_ROOT . '/library/google-api-php-client/src/contrib/Google_TranslateService.php';

class GoogleTranslator
{
    private $developer_key;

    const PROVIDER = "google";
    const SUCCESS = "success";
    const FAILURE = "failure";
    const TRANSLATE_SUCCESS_MESSAGE = 'text translation successful';

    public function __construct()
    {
        $this->developer_key = '<DEVELOPER KEY HERE>';
    }

    public function translate($text, $source_language, $target_language)
    {
        try {
            $client = new \Google_Client();
            $client->setApplicationName('Google Translate PHP Starter Application');

            $client->setDeveloperKey($this->developer_key);
            $service = new \Google_TranslateService($client);

            $optional_parameters = array('source' => $source_language);

            $translated_text = $service->translations->listTranslations($text, $target_language, $optional_parameters);
            return array('translation' => $translated_text['translations'][0]['translatedText'],
                'provider' => self::PROVIDER,
                'status' => self::SUCCESS,
                'message' => self::TRANSLATE_SUCCESS_MESSAGE);
        } catch (\Exception $e) {
            error_log($e->getMessage() . " FOR GET TRANSLATION CALL", "GOOGLE TRANSLATE API");
            $res = array('translation' => '',
                'provider' => self::PROVIDER,
                'status' => self::FAILURE,
                'message' => $e->getMessage());
            return $res;
        }
    }
}
