Using string to change into array but the string is details extracted from Oanda.com

Question

I was trying to get the currency rate from Oanda.com . because the exchange rate is really standard compared to Yahoo. Api .

So now I am able to get the details which is in some kind of string . I wanted to separate them and use the exact currency rate i want lik USD/CSR .

<?php
    $code=file_get_contents('http://www.oanda.com/embedded/converter/show/b2FuZGFlY2N1c2VyLy9vYW5kYV9ob21lX3BhZ2U=/0/en/');    
    $tmp=explode('<script type="text/javascript">var rates =',$code);
    $tmp=explode('</script>',$tmp[1]);
    $array=trim($tmp[0]);
    var_dump($array);
    $array1 =explode('pairs',$array);
    var_dump($array1[0]);
    var_dump($array1[1]);
?>
