Many-many thanks to jmathai , ToonMariner , experimentX for precious advice.
But i have got the simple solution
public function getCountryIp()
{
$currency = new Zend_Currency();
$countryCode = $this->getCountryFromIP();
$currencyCode = $currency->getCurrencyList($countryCode);
$localCurrency = $this->currency('USD',$currencyCode[0],50);
$var['currencyCode'] = $currencyCode[0];
$var['currency'] = $localCurrency;
return $var;
}
//use to convert currency
public function currency($from_Currency, $to_Currency, $amount)
{
$amount = urlencode($amount);
$from_Currency = urlencode($from_Currency);
$to_Currency = urlencode($to_Currency);
$url = "http://www.google.com/ig/calculator?hl=en&q=$amount$from_Currency=?$to_Currency";
$ch = curl_init();
$timeout = 0;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$rawdata = curl_exec($ch);
curl_close($ch);
$data = explode('"', $rawdata);
$data = explode(' ', $data['3']);
$stripped = ereg_replace("[^A-Za-z0-9.\+]", "", $data['0']);//remove special char
return round($stripped,3);
// $var = $data['0'];
// return $var;
// return round($var, 8);
}
//get ip-address and show country code
public function getCountryFromIP()
{
$ip = $_SERVER['REMOTE_ADDR'];
$country = exec("whois $ip | grep -i country"); // Run a local whois and get the result back
//$country = strtolower($country); // Make all text lower case so we can use str_replace happily
// Clean up the results as some whois results come back with odd results, this should cater for most issues
$country = str_replace("country:", "", "$country");
$country = str_replace("Country:", "", "$country");
$country = str_replace("Country :", "", "$country");
$country = str_replace("country :", "", "$country");
$country = str_replace("network:country-code:", "", "$country");
$country = str_replace("network:Country-Code:", "", "$country");
$country = str_replace("Network:Country-Code:", "", "$country");
$country = str_replace("network:organization-", "", "$country");
$country = str_replace("network:organization-usa", "us", "$country");
$country = str_replace("network:country-code;i:us", "us", "$country");
$country = str_replace("eu#countryisreallysomewhereinafricanregion", "af", "$country");
$country = str_replace("", "", "$country");
$country = str_replace("countryunderunadministration", "", "$country");
$country = str_replace(" ", "", "$country");
return $country;
}
