Add into database translated content

Hello wordpress, hello everybody!

I have a problem, i have a function to translate my content from french into italian language.

But i want, when i create a new post in french language to translate it automatically into italian language and after that to add it into database.

There is the function

function mycurl($url,$post){
	$ch = curl_init();
	$timeout = 0; // set to zero for no timeout
	$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
	curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
	curl_setopt ($ch, CURLOPT_URL,$url);
	curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
	curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
	curl_setopt($ch, CURLOPT_POST, 4);
	$file_contents = curl_exec($ch);
	curl_close($ch);
	$lines = array();
	$lines = explode("\n", $file_contents);
	$results = $lines ;
	$results = implode("", $results);
	return $results;
	}

	function my_translator($post_content){
	$url   = "http://translate.google.com/translate_t";
	$content=urlencode($post_content);
	$data="?hl=en|fr&text=".$content;
	$results= mycurl($url,$data);
	preg_match_all('/<textarea name=utrans wrap=SOFT dir="ltr" rows=5 id=suggestion>(.*?)\<\/textarea>/s', $results, $matches);
	$content=urlencode($matches[1][0]);
	return $matches[1][0];
	}

If somebody can help me, i will appreciate this!

Thank you!
