Phoenix	It won't be possible to have something like [curr]$100[/curr] since that could be canadian, american, australian (etc) dollars. It would have to be [curr=USD]100[/curr], and then you have another table containing the currency prefixes and have them added before the number. I don't really see what the problem is though. Where do you need the regex?

Stealth	Here is a function I wrote based off of Phoenix's code. It uses Google, but I wrote a fail safe in to it just in case it breaks someday. Just remember to replace "somebody@example.com" with a real email address. <?php // Sample Usage echo convert_currency("50", "USD", "GBP"); // Convery Currency Function function convert_currency($amount, $from, $to) { // Query Google $source = file_get_contents("https://www.google.com/search?q=".$amount."+".$from."+in+".$to); // Extract Data From Page preg_match("/calc_img\.gif\swidth=40\sheight=30\salt=\"\"><\/td><td> <\/td><td\snowrap\sdir=ltr><h2\sclass=r><font\ssize=\+1><b>([^<]+)<\/b><\/h2>/", $source, $matches); // Grab Result $result = $matches[0]; // Get Rid of Junk $result = str_replace("calc_img.gif width=40 height=30 alt=\"\"></td><td> </td><td nowrap dir=ltr><h2 class=r><font size=+1><b>", "", $result); $result = str_replace("</b></h2>", "", $result); // We just want the converted to part. $results = explode("= ", $result); // Get Final Result $result = $results[1]; if (!empty($result)) { return $result; } else { mail("somebody@example.com", "Converter broke!", "The converter broke. sigh"); return "Unable to convert value."; } } ?> --v -=-=- Quit posting and try Google.

Jayenkai	I know that [curr]$ won't always work, but 99% of the time it will! I would, obviously, be adding USD as well.. Look at the big array, it has them all there!! I was trying to get the simplest form of written currency.. hence why I wrote "Lets take it to it's most basic.." Blinkin' munky's, it's like nobody read what I put there! Having a good think about it at work, I figured I'll do it without regex, and just flick through the possibilities manually.. Probably the best bet. Going to have to do it between where it pulls out the code box stuff, though, 'cos otherwise it'll be plucking all your variables up as money!! -=-=- ''Load, Next List!''

Phoenix	it's like nobody read what I put there! I've read it ten times and I still don't get it

Evil Roy Ferguso	This accepts things in the form [ curr ]currencyamount[ /curr ]. It may not be the fastest way of doing things, but it's pretty short and readable. \|edit\| Ack, just noticed the conversions were being done backwards. Should be fine now. \|edit\| New version further down!

Jayenkai	Ta, I haven't had a chance to play with it, yet though.. Busy busy week of Xmas! Bah, humbug!! -=-=- ''Load, Next List!''

Jayenkai	Thanks. And, although I'm sure that's easy to implement, I'm not in any kind of Socoder-script-tweak position right now! Knowing me, If I download the file over PHP, tweak it, then upload it again, I'd probably forget I ever did it.. And then once all my old files are up and running again, I'd end up with 2 versions of Socoder, and inevitably overwrite all the new work I'd done! It'll have to wait, I'm afraid.. -=-=- ''Load, Next List!''

Evil Roy Ferguso	Oh, that's not a problem. I revised my code because I have obsessive-compulsive disorder and noticed a major inefficiency in my old solution; there's no hurry to add the code, and even then, I honestly don't mind if it's never used -- it's just that having the old version posted was bothering me! To be perfectly honest, I think that having the currencypop is probably more trouble than it's worth, since Google happens to exist.
