19. And that’s it
Throw in a bit of PHP to turn the JSON into HTML
CSS to style it
Wrap it in your page template
eg: http://bluesmoon.info/foobar
Yahoo!7 Open Session – 11 May 2010 – #y7os YQL: Find more than just data

20. PHP
$json = http_get($missing_kids_url);
$o = json_decode($json, 1);
$children = $o[’query’][’results’]
[’locations’][’location’];
$child = array_rand($children);
print_404($child);
...
header(’HTTP/1.0 404 Not Found’);
