Ha ha .... ha! You think I didn't try Google? :p

I did find a few, but they required registring to some site. Blech! And even when I did, I didn't get an email for at least an hour. Actually, I stopped looking after that. I gave them my spam account anyway. ;)

When I tried using different key words I finally found some. I think the words were: Ajax, currency and converter. Pain in the ass trying to find somethings. :(

But I did find it. Thanks.

Ermmm. What currencies are you trying to convert?
Do you need them updated in real time?
I bet I could whip something up real fast.

HA-HA! (bully from the Simpsons) ;)

I've not tried it, but I would like it to convert all different types. Apperently, the one I've got and am still looking at will download a csv file from yahoo's finantial pages and then it will be able to convert and update using AJAX.

I'm still trying to get it to work. :(

You could do the same thing with mine: use fopen and fgetcsv to read the CSV file, and write the data to an associative array. Take the input currency, convert to a standard medium, and convert to your output currency.
I like the associative array method better, as it is easier to use: you don't need to keep track of every currency's exchange rate with every other currency (an n squared problem). Instead you keep track of every currency in relation to a base (in my case, dollars) and do all conversions with that.
The basic algorithm would be:

(source amount) / (source rate) * (currency rate)

you could at least have made it possible for users to specify the conversion rates ...

You think you're pretty smart, what with your 5000 posts eh? Won't be feeling so spiffy once I go and delete all of your posts. You'll be sitting there with roughly a dozen in your name.

Don't forget my arm is longer than yours and reaches all the small and nasty corners.
