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 = ""; 
$google_translator_url = "http://translate.google.com/translate_t?langpair=".urlencode($this->opts["language_pair"])."&;"; 
$google_translator_data .= "text=".urlencode($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
PHP的就这里，参见了部分同学的部分代码。具体忘了。
这段代码不好。。。但可以用，懒得管啦。。
