I was bored and needed something like this so i made it and thought i'd post my result

An even nicer function could be exchange rates, since All the currencies have different rates. It'd be cool if you could grab each one from a site that updates them, but current ones are fine

I actually was thinking about doing a exchange rate one but the exchange rates are updated all the time there's not much point really.

You know any sites with API's that you can grab the current exchange rate from?

[LordDan]

function exchangeRate( $amount, $currency, $exchangeIn )
{
   $googleQuery = $amount . ' ' . $currency . ' in ' . $exchangeIn;
   $googleQuery = urlEncode( $googleQuery );
   $askGoogle = file_get_contents( 'http://www.google.com/search?q=' . $googleQuery );
   $askGoogle = strip_tags( $askGoogle );
   $matches = array();
   preg_match( '/= (([0-9]|\.|,|\ )*)/', $askGoogle, $matches );
   return $matches[1] ? $matches[1] : false;
}

echo exchangeRate( 1000, 'euro', 'dollars' );

 

This what you mean?

never thought of it that way, thanks for that LordDan

i made a function like this its in the mccodes free mods it has the conversion rate too

wops didnt see the auto updating

[Karlos94]

Why not do it a nice simple way? Using a regularly updated XML file with the latest exchange rates, they aren't that hard to find. ;)

[LordDan]

Because I didn't write it, I just did a search and posted as reference ^^ I've never needed such a function myself..

Oh I see, but the idea is there now, in case someone wishes to do it the way I said.
