【IT168 技术文档】这里我还是接上话使用Google的translate工具翻译 .NET translate API的一篇文字，上篇是c#实现的，我这里再用PHP实现一下。新建一个ANSI的PHP文件，然后创建一个类：

header("Content-Type: text/html; charset=utf-8");

class Google_API_translator{
    public $opts = array("text" => "", "language_pair" => "en|it");
    public $out = "";

    function setOpts($opts) {
        if($opts["text"] != "") $this->opts["text"] = $opts["text"];
        if($opts["language_pair"] != "") $this->opts["language_pair"] = $opts["language_pair"];
    }

    function translate() {
        $this->out = "";
        $google_translator_url = "
        $google_translator_data .= "text=".urlencode($this->opts["text"]);
        $gphtml = $this->postPage(array("url" => $google_translator_url, "data" => $google_translator_data));
        $out = substr($gphtml, strpos($gphtml, "

"));
        $out = substr($out, 29);
        $out = substr($out, 0, strpos($out, "
"));
        $this->out = utf8_encode($out);
        return    $this->out;
    }

    function postPage($opts) {
        $html ='';
        if($opts["url"] != "" && $opts["data"] != "") {
            $ch = curl_init($opts["url"]);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_HEADER, 1);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            curl_setopt($ch, CURLOPT_TIMEOUT, 15);
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $opts["data"]);
            $html = curl_exec($ch);
            if(curl_errno($ch)) $html = "";
            curl_close ($ch);
        }
        return $html;
    }
}
?>

使用的时候

$g = new Google_API_translator();
$g->setOpts(array("text" => "Cjjer是天才", "language_pair" => "zh-CN|en"));
$g->translate();
echo $g->out;
?>

这样就可以了，输出：Cjjer is genius
