谷歌翻译 google translation api
长孙兴德
以下任何一个实例均可实现谷歌翻译功能：
实例 1：
<?php
function translate( $text, $destLang = 'zh-cn', $srcLang = 'en' ) {
$text = urlencode( $text );
$destLang = urlencode( $destLang );
$srcLang = urlencode( $srcLang );
$trans = @file_get_contents( "http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q={$text}&langpair={$srcLang}|{$destLang}" );
$json = json_decode( $trans, true );
if( $json['responseStatus'] != '200' ) return false; else return $json['responseData']['translatedText'];
}
echo translate('Google Translate is probably one of the best online translators around. Here’s how to integrate it into your scripts.');
?>
实例 2：
<?php
class Google_Translate_API {
/**
* Translate a piece of text with the Google Translate API
* @return String
* @param $text String
* @param $from String[optional] Original language of $text. An empty String will let google decide the language of origin
* @param $to String[optional] Language to translate $text to
*/
function translate($text, $from = '', $to = 'en') {
$url = 'http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q='.rawurlencode($text).'&langpair='.rawurlencode($from.'|'.$to);
$response = file_get_contents(
$url,
null,
stream_context_create(
array(
'http'=>array(
'method'=>"GET",
'header'=>"Referer: http://".$_SERVER['HTTP_HOST']."/\r\n"
)
)
)
);
if (preg_match("/{\"translatedText\":\"([^\"]+)\"/i", $response, $matches)) {
return self::_unescapeUTF8EscapeSeq($matches[1]);
}
return false;
}
/**
* Convert UTF-8 Escape sequences in a string to UTF-8 Bytes
* @return UTF-8 String
* @param $str String
*/
function _unescapeUTF8EscapeSeq($str) {
return preg_replace_callback("/\\\u([0-9a-f]{4})/i", create_function('$matches', 'return html_entity_decode(\'&#x\'.$matches[1].\';\', ENT_NOQUOTES, \'UTF-8\');'), $str);
}
}
// example usage
$text = 'Welcome to my website.';
$trans_text = Google_Translate_API::translate($text, 'en', 'zh-cn');
if ($trans_text !== false) {
echo $trans_text;
}
?>
