Answer 1

You can read the conversion rate like this:

<?php   

$x = simplexml_load_file('http://www.tcmb.gov.tr/kurlar/today.xml');

// Use GBP as an example
$code = 'GBP';

$nodes = $x->xpath('//Currency[@CurrencyCode="' . $code . '"]');

echo 'Buying Rate for ' . $code . 'is ' . (string)$nodes[0]->BanknoteBuying;


?>

Answer 2

$site = file_get_contents("http://www.tcmb.gov.tr/kurlar/today.xml"); 
preg_match_all("'EURO</CurrencyName><ForexBuying>(.*)</ForexBuying><ForexSelling>(.*)<CrossRateOther>(.*)<'U", $site, $durum);
preg_match_all("'POUND STERLING</CurrencyName><ForexBuying>(.*)</ForexSelling>(.*)<CrossRateOther>(.*)<'U", $site, $GBP);
$tl     = $durum[1][0]; 
$dolar  = $durum[3][0];
