im intermediate programmer so want to know about the following site currency conversion method on this website http://www.astleyclarke.com/ you will notice the $ , pound and euro symbols in the header and when we click on it all currency changes to respective rates. how can i implement the similar functionality in my website?
the first step is to estabilish a variable called currency then you might have a database table with each currency values after that - as you can see - take the currency wanted to be used from a $_GET paramater and list the content depending on it's value
