When you feel you may want to use the requested url with all the get variables passed (just the way it is in the browser’s address bar), you can use the following code snippet:
private function getCurPageURL() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; }
A much better solution to this exists at http://epicwhale.org/blog/2010/12/currency-conversion-using-php/. We highly recommended you use that instead.
This is a very powerful and light weight PHP class that lets you convert between 65+ currencies using Google Finance (http://www.google.com/finance/converter)
Example:
CurrencyRates::Convert('USD', 'INR');
Output:
49 //Since $1 is Rs. 49
