1) Google translation interface

Google provides a translation API interface, see https:/ /developers.google.com/translate/v2/getting_started

but

Google Translate API is a paid service.

so

Want to use Google Translate API free charge requires another way

Google provides a free online translation function. Therefore, you can send a translation request to Google through the Web, receive its HTML return, and then obtain the translated text by analyzing the HTML. .

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=&#39;世界，你好！&#39;;INPUT_TOOL_PATH=&#39;//www.google.com&#39;;
	$mode= ("/TRANSLATED_TEXT=&#39;(.*)&#39;;INPUT_TOOL_PATH/");
	if (preg_match($mode,$html,$out)){
		return $out[1];//ret;
	}
}

What’s more, someone discovered that you can get a json return by http://translate.google.com/translate_a/t?client=pinteracting with Google, which is equivalent to API usage

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 Translate Interface Example: http://download.csdn.net/detail/d_eng/6563915

There are two issues to pay attention to here

1) Encoding problem, the examples all use utf-8, even the attributes of the PHP file are utf-8

2) Google problem, Google does not guarantee that it can always be connected in China, although there are multiple links google.com/google.cn/google.com.hk

2) WeChat call

With the interface, it is simple to call in WeChat

Interface file translate_func. php (save as utf-8)

t)&default code=GBK
		function translate_json()
