* 注意：如果翻译文本为UTF-8编码，则要删去mb_convert_encoding函数

class Google_API_translator {

public $url = “http://translate.google.com/translate_t”;

public $text = “”;//翻译文本

public $out = “”; //翻译输出

function setText($text){

$this->text = $text;

}

function translate() {

$this->out = “”;

$gphtml = $this->postPage($this->url, $this->text);

//提取翻译结果

$out = substr($gphtml, strpos($gphtml, “

“));

$out = substr($out, 29);

$out = substr($out, 0, strpos($out, “

));

$this->out = $out;

return $this->out;

}

function postPage($url, $text) {

$html =”;

if($url != “” && $text != “”) {

$ch = curl_init($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);

*hl – 界面语言，此处无用。

*langpair – src lang to dest lang

*ie – urlencode的编码方式?

*text – 要翻译的文本

$fields = array(‘hl=zh-CN’, ‘langpair=zh-CNen’, ‘ie=UTF-8′,’text=’.urlencode(mb_convert_encoding($text, ‘UTF-8′, ‘GB2312′)));

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, implode(‘&’, $fields));

$html = curl_exec($ch);

if(curl_errno($ch)) $html = “”;

curl_close ($ch);

}

return $html;

}

//just for test

$g = new Google_API_translator();

$g->setText(“我爱php100!”);

$g->translate();

echo $g->out;
