  function currency_format($amount, $currency='') {
$currency_array = array(
	'GBP' => '£', 
	'JPY' => '¥', 
	'CNY' => '¥', 
	'EUR' => '€', 
	'USD' => '$',
	'' => ''
);
     if ( (ctype_alpha($currency) OR empty($currency)) && array_key_exists($currency, $currency_array) && ctype_digit($amount) ) {
	$ret_txt = '<span style="font-weight: bold;">'.$currency_array[$currency].'</span>'.number_format($amount);
     } else {
	$ret_txt = FALSE;
     }
return $ret_txt;
 }
$var = '2001';
echo currency_format($var, 'USD'); // outputs $2,001
echo currency_format($var, 'GBP'); // outputs £2,001
echo currency_format($var, 'JPY'); // outputs ¥2,001
echo currency_format($var, 'CNY'); // outputs ¥2,001
echo currency_format($var, 'EUR'); // outputs €2,001
echo currency_format($var); // outputs 2,001
echo currency_format($var, 'lol'); // fails
echo currency_format('+'.$var, 'USD'); // fails

function exchangeRate( $amount, $currency, $exchangeIn )
{
   $googleQuery = $amount . ' ' . $currency . ' in ' . $exchangeIn;
   $googleQuery = urlEncode( $googleQuery );
   $askGoogle = file_get_contents( 'http://www.google.com/search?q=' . $googleQuery );
   $askGoogle = strip_tags( $askGoogle );
   $matches = array();
   preg_match( '/= (([0-9]|\.|,|\ )*)/', $askGoogle, $matches );
   return $matches[1] ? $matches[1] : false;
}

echo exchangeRate( 1000, 'euro', 'dollars' );
