php调用google在线翻译功能

从中文到英语

class Google_API_translator {

public $out = "";

    function translate() {
        $this->out = "";
        $text = urlencode("计算机");//要翻译的单词

        $google_translator_url = "http://translate.google.com/translate_a/t?client=t&text=".$text."&sl=zh_CN&tl=en";

        echo $google_translator_url;
        $gphtml = $this->postPage(array("url" => $google_translator_url));

        $this->out = $gphtml;

return $this->out;
    }
    function postPage($opts) {
        $html = "";

if($opts["url"] != "") {
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $opts["url"]);

            $html = curl_exec($ch);

if(curl_errno($ch)) $html = "";
            curl_close ($ch);
        }

return $html;
    }
}

$g = new Google_API_translator();

$g->translate();

从英语到中文

class Google_API_translator {

public $out = "";

    function translate() {
        $this->out = "";
        $text = urlencode("computer");//要翻译的单词

        $google_translator_url = "http://translate.google.com/translate_a/t?client=t&text=".$text."&sl=en&tl=zh_CN";

//拼凑google翻译的api url         
        $gphtml = $this->postPage(array("url" => $google_translator_url));

        $this->out = $gphtml;

return $this->out;
    }
    function postPage($opts) {
        $html = "";

if($opts["url"] != "") {
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $opts["url"]);

            $html = curl_exec($ch);

if(curl_errno($ch)) $html = "";
            curl_close ($ch);
        }

return $html;
    }
}

$g = new Google_API_translator();

$g->translate();

很完美，返回的结果中没有任何编码问题。从google返回的中文编码完全正确。
