function detect_city($ip) {
$default = 'UNKNOWN';
if (!is_string($ip) || strlen($ip) < 1 || $ip == '127.0.0.1' || $ip == 'localhost')
$ip = '8.8.8.8';
$curlopt_useragent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)';

Created December 3, 2013 16:44
Convert currencies using cURl and Google Converting currencies isn’t very hard to do, but as the currencies fluctuates all the time, we definitely need to use a service like Google to get the most recent values. The currency() function take 3 parameters: from, to, and sum.
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)");

$lines = file('http://google.com/');
foreach ($lines as $line_num => $line) {
// loop thru each line and prepend line numbers
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br>\n";
}
