One of my students wants to search WordPress.com entries in her project.  Here’s how!

<?php
// Change this!
$query = "There's no such name as Brahbrah";

// WordPress supplies search results in JSON format.
$url = "http://en.search.wordpress.com/?f=json&q=".urlencode($query);
$contents = file_get_contents($url);
$posts = json_decode($contents);

// Now loop through all of the results
if($posts != NULL)
foreach($posts as $post):
?>
	<!-- Here is where all of the entries get printed out -->
	<h2><a href="<?php echo $post->link; ?>"><?php echo $post->title; ?></a></h2>

	<p>by <?php echo $post->author; ?> on
	<?php echo date('l jS \of F Y h:i:s A', $post->epoch_time); ?></p>

	<p><?php echo $post->content; ?></p>

<?php endforeach; ?>

PS: If your server complains about ‘file_get_contents’, paste in this function and replace ‘file_get_contents’ with ‘curl_get_contents’

function curl_get_contents($url) {
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)');
	curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com');
	curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
	curl_setopt($ch, CURLOPT_AUTOREFERER, true);
	$data = curl_exec($ch);
	curl_close($ch);
	return $data;
}
