Question

I want to extract string between html tags and convert it into other language using google api and to append the string with html tags.

For example,

<b>This is an example</b>

I want to extract the string “This is an example” and convert it into other language and then again append the string with bold tag.

Could anyone know how to proceed with this?

Here’s a working example of using the Google API to translate server side. The function takes a string as an input and strips HTML tags from it before translating.

The languages are passed in as arguments.

<?php
// This function translates a string $source written in the $fromLang languages to the $toLang language.
function translateTexts($source, $fromLang, $toLang)
{

    /* Language choices: 'AFRIKAANS' : 'af', 'ALBANIAN' : 'sq', 'AMHARIC' : 'am', 'ARABIC' : 'ar', 'ARMENIAN' : 'hy', 'AZERBAIJANI' : 'az', 'BASQUE' : 'eu', 'BELARUSIAN' : 'be', 'BENGALI' : 'bn', 'BIHARI' : 'bh', 'BRETON' : 'br', 'BULGARIAN' : 'bg', 'BURMESE' : 'my', 'CATALAN' : 'ca', 'CHEROKEE' : 'chr', 'CHINESE' : 'zh', 'CHINESE_SIMPLIFIED' : 'zh-CN', 'CHINESE_TRADITIONAL' : 'zh-TW', 'CORSICAN' : 'co', 'CROATIAN' : 'hr', 'CZECH' : 'cs', 'DANISH' : 'da', 'DHIVEHI' : 'dv', 'DUTCH': 'nl',  'ENGLISH' : 'en', 'ESPERANTO' : 'eo', 'ESTONIAN' : 'et', 'FAROESE' : 'fo', 'FILIPINO' : 'tl', 'FINNISH' : 'fi', 'FRENCH' : 'fr', 'FRISIAN' : 'fy', 'GALICIAN' : 'gl', 'GEORGIAN' : 'ka', 'GERMAN' : 'de', 'GREEK' : 'el', 'GUJARATI' : 'gu', 'HAITIAN_CREOLE' : 'ht', 'HEBREW' : 'iw', 'HINDI' : 'hi', 'HUNGARIAN' : 'hu', 'ICELANDIC' : 'is', 'INDONESIAN' : 'id', 'INUKTITUT' : 'iu', 'IRISH' : 'ga', 'ITALIAN' : 'it', 'JAPANESE' : 'ja', 'JAVANESE' : 'jw', 'KANNADA' : 'kn', 'KAZAKH' : 'kk', 'KHMER' : 'km', 'KOREAN' : 'ko', 'KURDISH': 'ku', 'KYRGYZ': 'ky', 'LAO' : 'lo', 'LATIN' : 'la', 'LATVIAN' : 'lv', 'LITHUANIAN' : 'lt', 'LUXEMBOURGISH' : 'lb', 'MACEDONIAN' : 'mk', 'MALAY' : 'ms', 'MALAYALAM' : 'ml', 'MALTESE' : 'mt', 'MAORI' : 'mi', 'MARATHI' : 'mr', 'MONGOLIAN' : 'mn', 'NEPALI' : 'ne', 'NORWEGIAN' : 'no', 'OCCITAN' : 'oc', 'ORIYA' : 'or', 'PASHTO' : 'ps', 'PERSIAN' : 'fa', 'POLISH' : 'pl', 'PORTUGUESE' : 'pt', 'PORTUGUESE_PORTUGAL' : 'pt-PT', 'PUNJABI' : 'pa', 'QUECHUA' : 'qu', 'ROMANIAN' : 'ro', 'RUSSIAN' : 'ru', 'SANSKRIT' : 'sa', 'SCOTS_GAELIC' : 'gd', 'SERBIAN' : 'sr', 'SINDHI' : 'sd', 'SINHALESE' : 'si', 'SLOVAK' : 'sk', 'SLOVENIAN' : 'sl', 'SPANISH' : 'es', 'SUNDANESE' : 'su', 'SWAHILI' : 'sw', 'SWEDISH' : 'sv', 'SYRIAC' : 'syr', 'TAJIK' : 'tg', 'TAMIL' : 'ta', 'TATAR' : 'tt', 'TELUGU' : 'te', 'THAI' : 'th', 'TIBETAN' : 'bo', 'TONGA' : 'to', 'TURKISH' : 'tr', 'UKRAINIAN' : 'uk', 'URDU' : 'ur', 'UZBEK' : 'uz', 'UIGHUR' : 'ug', 'VIETNAMESE' : 'vi', 'WELSH' : 'cy', 'YIDDISH' : 'yi', 'YORUBA' : 'yo', 'UNKNOWN' : ''  */

    // Creating the query URL
    $url = "http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=" . urlencode($source) . "&langpair=" . $fromLang . "%7C" . $toLang;

    // send translation request
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     
    $response = curl_exec($ch);
    curl_close($ch);

    // now, process the JSON string
    $json = json_decode($response, true);

    // If response status is okay
    if ($json['responseStatus'] == 200)
    {
        $translated = $json['responseData']['translatedText'];
    } else 
    {
        $translated = "****Error. Couldn't translate.****";
    }     
    // return translated text
    return $translated;
}

// Get the string you want to translate
$string = "<b>This is an example</b>";
// Strip the HTML tags from the strip and translate it.
echo translateTexts(strip_tags($string), 'en', 'es');

?>

When you run the code above, you should add in a proper self identification to the header.
