Using Yahoo’s API to convert currencies with PHP

I have been looking around Yahoo Developer Network for this but found nothing relating to using the Currency Converter API.

You can make something similar to convert any currency to another currency using the Yahoo! database!

Here is what I came up with:

< ?php
$from   = 'USD'; //US Dollar
$to     = 'PHP'; //to Philippine Peso
$url = 'http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s='. $from . $to .'=X';
$handle = @fopen($url, 'r');
if ($handle) {
    $result = fgets($handle, 4096);
$array = explode(',',$result);
  array(4) {
  string(10) ""USDPHP=X""
  string(6) "47.125"
  string(11) ""10/3/2008""
  string(10) ""5:03pm"

This is the simplest example I could give. And it works!

    It’s gr8 .. this is what I am looking for.

    Do you have any idea about the currency type it support? Also, can i use this frequently? I mean is yahoo allow me to request this URL thousand times a day?

  5. Wenbert says:

    @ashish You can go to their finance website see what types of currencies they support. But I am guessing they can convert any currency.

    Yahoo has unlimited resources ;) so you can use this as much as you want. But the smart thing to do is to “fetch” the data and store it in your database – you can use a cronjob to automatically fetch the currencies – autofetch the data every 30 minutes. Then, you query your database instead of querying Yahoo for every request. It will be safer this way.

    Hello Friends,

    Is their a single URL bu which I can fetch the exchange rates of all the currency??
    I mean I send one URL and response should be base currency and all other currency in its respect…


  15. Wenbert says:

    @chits, I am not sure. But using the single URL, i would store the values in my database then update my database with a cronjob. It would also be faster on your side because you will be querying your own database instead of the URL.

  16. Chits says:

    Thanks Wenbert,

    Actually I was making a application(currency converter) which supports many currencies..now the suggestion is good but the only problem is I have to make multiple request in a loop (when doing currency update) and keep track of all of the request..in a way a bit more of work ..

  17. Chris W says:

    I’m looking similar to this for long..
