Dunno if this will be of any use, but i have quickly botched a class to translate words using Google Translate.
Its a bit of a mess but it works, it also uses CURL and PHP DOM XPath.
PHP Code:
<?php
error_reporting(0);
class translatorException extends Exception {}
class translator
{
private $m_szLangPair;
private $m_szText;
const BASE_URL = 'http://translate.google.com/translate_t?langpair=';
private function throwException($szMessage) { throw new translatorException($szMessage); }
private function getHTML()
{
$pCurl = curl_init(self::BASE_URL . $this->m_szLangPair);
curl_setopt($pCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($pCurl, CURLOPT_HEADER, 1);
curl_setopt($pCurl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($pCurl, CURLOPT_TIMEOUT, 15);
curl_setopt($pCurl, CURLOPT_POST, 1);
curl_setopt($pCurl, CURLOPT_POSTFIELDS, 'text=' . $this->m_szText);
$szHtml = curl_exec($pCurl);
if($szError = curl_error($pCurl))
{
curl_close ($pCurl);
$this->throwException($szError);
}
return $szHtml;
}
public function __call($szCall, $aArgs)
{
preg_match('/^([a-z]{2})2([a-z]{2})$/i', $szCall, $aMatches)
or $this->throwException('Malformed system call,
[lang]2[lang] e.g. en2it (ENglish to ITalian)');
$this->m_szLangPair = urlencode($aMatches[1] . '|' . $aMatches[2]) . '&';
is_null($aArgs) || !is_array(reset($aArgs))
or $this->throwException('You have entered either a NULL or incompatable type into the system,
please only pass in a string to be converted');
$this->m_szText = urlencode((string)reset($aArgs));
$pDoc = new DomDocument;
$pDoc->loadHTML($this->getHTML());
$pXpath = new DOMXPath($pDoc);
return $pXpath->query('//div[@id="result_box"]')->item(0)->nodeValue;
}
}
To use:
PHP Code:
try
{
$lang = new translator;
header('Content-type: text/html; charset="utf-8"');
echo $lang->en2hi('hello');
}
catch (Exception $e)
{
echo $e->getMessage();
}
