Answer 1

 $amount=100; //Your amount
 $from_currency = "INR";
 $to_currency = "USD";
 $from_currency = urlencode($from_currency);
 $to_currency = urlencode($to_currency);
 $url = "https://www.google.com/search?q=".$from_currency."+to+".$to_currency;
 $get = file_get_contents($url);
 $data = preg_split('/\D\s(.*?)\s=\s/',$get);
 $exhangeRate = (float) substr($data[1],0,7);
 $converted_amount  = $amount*$exhangeRate;




please use $url = "https://www.google.com/search?q=".$from_currency."+to+".$to_currency;
