TalkPHP - language converter in php

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();
}
