1）Google翻译接口2）微信调用3）效果展示----------------------------------------------------------------------------------------1）Google翻译接口Google提供翻译的API接口,参见https://developers.google.com/translate/v2/getting_startedbutGoogle Translate API is a paid service.so想利用Google Translate API free charge 就要另外想办法了Google提供免费的在线翻译功能,因此,可以通过Web发送翻译请求给Google,接收它的html返回,然后,通过分析html获取翻译后的文字.

function translate_web($text, $language="auto|en") {   	if (empty($text)) return false;   	  	$url = "http://google.cn/translate_t?ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);	      	$html=file_get_contents($url);  	  	// parse html   	// html souce: TTS_TEXT_SIZE_LIMIT=100;TRANSLATED_TEXT='世界，你好！';INPUT_TOOL_PATH='//www.google.com';  	$mode= ("/TRANSLATED_TEXT='(.*)';INPUT_TOOL_PATH/");  	if (preg_match($mode,$html,$out)){  		return $out[1];//ret;  	}  }

更有甚者,有人发现通过http://translate.google.com/translate_a/t?client=p与Google交互可以得到json返回,这就相当于API使用了

function translate_json($text, $language="auto|en") {   	if (empty($text)) return false;   	  	$url = "http://translate.google.cn/translate_a/t?client=p&ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);  	$json=file_get_contents($url);  	$data = json_decode($json);  	return $data->sentences[0]->trans;	  }

Google翻译接口示例: http://download.csdn.net/detail/d_eng/6563915这里要注意的有两个问题1)编码问题,例子中都采用utf-8,连php文件的属性都是utf-82)google问题,google在中国不保证一直能连上,虽然有多个链接 google.com/google.cn/google.com.hk2）微信调用有了接口,在微信中调用就简单了接口文件 translate_func.php (save as utf-8)

<?php   /*  	2 Google Translate interface    	1)	Google Translate WEB IF  		get translated text by parsing return html which code is GBK  		function translate_web()  	2)	Google Translate JSON IF  		get translated text which format=json(set client<>t)&default code=GBK  		function translate_json()    	 d_eng (sh109419@163.com)  	 2013-11-16    */     /*  	Google Translate WEB IF  	get translated text by parsing return html which code is GBK   */     //header("Content-Type:text/html; charset=utf-8");      function translate_web($text, $language="auto|en") {   	if (empty($text)) return false;   	  	$url = "http://google.cn/translate_t?ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);	          $html=file_get_contents($url);  	  	// parse html   	// html souce: TTS_TEXT_SIZE_LIMIT=100;TRANSLATED_TEXT='世界，你好！';INPUT_TOOL_PATH='//www.google.com';  	$mode= ("/TRANSLATED_TEXT='(.*)';INPUT_TOOL_PATH/");  	if (preg_match($mode,$html,$out)){  		return $out[1];//ret;  	}  }     function translate_json($text, $language="auto|en") {   	if (empty($text)) return false;   	  	$url = "http://translate.google.cn/translate_a/t?client=p&ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);  	$json=file_get_contents($url);  	$data = json_decode($json);  	return $data->sentences[0]->trans;	  }    function  with_chinese($text){              return  preg_match('/[\x7f-\xff]/',$text);  }            function translate($text) {   	if (with_chinese($text)) {  		return translate_json($text,'zh-CN|en');  	} else {  		return translate_json($text,'en|zh-CN');  	}  }    ?>

调用代码片段

if  ($RX_TYPE=="text") {                        include("translate_func.php");                        $resultStr = $this->responseText($postObj,  translate(trim($postObj->Content)));                    }
