[SOLVED] dynamic reload

[NickG21]

hey everyone, i have a pricing site that i am trying to make have capabilities of reloading with all prices in euros, lyra, etc.... and back to USD depending on the symbol clicked by the user.  is there any php scripts written that will produce a result like this? if not, could someone try and point me in a general direction of how to accomplish this?
thank you

Depend how much PHP you know

Personally, I would store the Currency in a Session
Then show the price Depending the the currency Session
For example

[code]
<?php
$CurrencySymbols = array( 1 => "\$", 2 => "€", 3 => "£");
//Examples Made Up
$CurrencyExchangeRate = array(1 => 0, 2 => 0.6, 3 => 0.4);

$_SESSION["CurrencyID"] = isset($_SESSION["CurrencyID"]) ? $_SESSION["CurrencyID"] : 1;

$ItemPrice = 80;

$CurrencyPrice = $ItemPrice * $CurrencyExchangeRate[$_SESSION["CurrencyID"];
echo $CurrencySymbols[$_SESSION["CurrencyID"].$CurrencyPrice;

?>
[/code]

and to change the CurrencyID
At the top of the script

[code]

if(isset($_GET["currencyID"])){
if(is_numeric($_GET["currencyID"]){
$_SESSION["CurrencyID"] = $_GET["currencyID"];
}
}

<a href='".$_SERVER['PHP_SELF']."?currencyID=1'>USD</a><br />
<a href='".$_SERVER['PHP_SELF']."?currencyID=2'>Euro</a><br />
<a href='".$_SERVER['PHP_SELF']."?currencyID=3'>British Sterling</a><br />
[/code]

if anyone can further elaborate for me on what exactly this code means with sessions i would appreciate it.  i understand what it is doing but do not understand exactly how it runs through and reloads the site with the altered prices??
thank you
