Currency Converter Using PHP

below function used to convert one currency to another

function get_conversion($cur_from,$cur_to){
if(strlen($cur_from)==0){
$cur_from = "USD";
}
if(strlen($cur_to)==0){
$cur_from = "PHP";
}
$host="finance.yahoo.com";
$fp = @fsockopen($host, 80, $errno, $errstr, 30);
if (!$fp)
{
$errorstr="$errstr ($errno)
\n";
return false;
}
else
{
$file="/d/quotes.csv";
$str = "?s=".$cur_from.$cur_to."=X&f=sl1d1t1ba&e=.csv";
$out = "GET ".$file.$str." HTTP/1.0\r\n";
$out .= "Host: www.yahoo.com\r\n";
$out .= "Connection: Close\r\n\r\n";
@fputs($fp, $out);
while (!@feof($fp))
{
$data .= @fgets($fp, 128);
}
@fclose($fp);
@preg_match("/^(.*?)\r?\n\r?\n(.*)/s", $data, $match);
$data =$match[2];
$search = array ("']*?>.*?'si","'<[\/\!]*?[^<>]*?>'si","'([\r\n])[\s]+'","'&(quot|#34);'i","'&(amp|#38);'i","'&(lt|#60);'i","'&(gt|#62);'i","'&(nbsp|#160);'i","'&(iexcl|#161);'i","'&(cent|#162);'i","'&(pound|#163);'i","'&(copy|#169);'i","'&#(\d+);'e");
$replace = array ("","","\\1","\"","&","<",">"," ",chr(161),chr(162),chr(163),chr(169),"chr(\\1)");
$data = @preg_replace($search, $replace, $data);
$result = split(",",$data);
return $result[1];
}//else
}//end get_conversion

$value =2;
$x = get_conversion('USD','EUR');
$x = $x * $value;

echo "Conversion Result : ".$x."";
?>

$value means 1,2 etc that means 1 USD = -- EUR
etc

below are the currency names

Installing Apache PHP and MySQL

PHP and MySQL are usually associated with LAMP (Linux, Apache, MySQL, PHP). However, most PHP developer ( including me ) are actually using Windows when developing the PHP application. So this page will only cover the WAMP ( Windows, Apache, MySQL, PHP ). You will learn how to install Apache, PHP, and MySQL under Windows platform.

The first step is to download the packages :

You should get the latest version of each packages. As for the example in this tutorial i'm using Apache 2.0.50 ( apache_2.0.50-win32-x86-no_ssl.msi ), PHP 4.3.10 ( php-4.3.10-Win32.zip ) and MySQL 4.0.18 ( mysql-4.0.18-win.zip ).

Now let's start the installation process one by one.

Go through below links for more details : -

Enable curl with XAMPP on Windows XP

To enable curl library with XAMPP we need to modify the php.ini files in our xampp folder.

1) Locate the following files:
C:\Program Files\xampp\apache\bin\php.ini
C:\Program Files\xampp\php\php.ini
C:\Program Files\xampp\php\php4\php.ini

2) Uncomment the following line on your php.ini file by removing the semicolon.

;extension=php_curl.dll

3) Restart your apache server.

4) Check your phpinfo if curl was properly enabled.
