Needing PHP5's simplexml_load_file function but have PHP4?

If you are using PHP Proxy to deal with Cross Domain Security issues with Adobe Flex for things such as RSS feeds but have PHP4 instead of PHP5 you can do the following.

PHP5 makes it looks so nice

$url = $_POST['url'];
$xml = simplexml_load_file($url, "r");
echo $xml->asXML();

PHP4's equivalent

$url = $_POST['url'];
$handle = @fopen($url, "r");
$buffer = fgets($handle, 4096);
echo $buffer;

Great news feed.

Interest Calculator

I had an job interview recently at one of the local financial institutions. As part of the application process I left the interview with a small exercise, asked to use a couple hours on it and send it back in. The exercise was to use a small high level specification, along with a table of rates data, to do a modest small technical design document and implementation of a calculator sitting behind a web service. I did the exercise and sent it in but thought to myself why not chuck a Flex interface on it.

For intended audience.
