However, I couldn't get it to work, maybe I'm just too impatient. There is a good script included in the article which doesn't account for backslashes and the @ symbol. This works quite well for me. (I know, it's bad practice!). I've copied the code and indented it for readability below (and changed the function name, I've tested it out on a live site).

function checkEmail($email)
	{
		//First, we check that there's one @ symbol,
		//and that the lengths are right.
		if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email))
			{
				//Email invalid because wrong number of characters
				//in one section or wrong number of @ symbols.
				return false;
			}
 
		//Split it into sections to make life easier
		$email_array = explode("@", $email);
		$local_array = explode(".", $email_array[0]);
 
		for ($i = 0; $i < sizeof($local_array); $i++)
			{
				if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&↪'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$",$local_array[$i]))
					{
						return false;
					}
			}
 
			//Check if domain is IP. If not,
			//it should be valid domain name
			if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1]))
				{
					$domain_array = explode(".", $email_array[1]);
					if (sizeof($domain_array) < 2)
						{
							return false; // Not enough parts to domain
						}
					for ($i = 0; $i < sizeof($domain_array); $i++)
						{
							if(!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|↪([A-Za-z0-9]+))$",$domain_array[$i]))
								{
									return false;
								}
						}
				}
		return true;
	}
 

If you find this script isn't conforming to correct standards, there's a more complex and updated one at google code:

//enter your last.fm username
$username = 'spahndirge';
//in seconds, how long to wait until your recently listened tracks are checked for new entries
$time = 300;
//this is the URL of the last.fm xml file of your profile
$lastfmFile = "http://ws.audioscrobbler.com/1.0/user/$username/recenttracks.xml";
//the number of tracks you want to display, this can't be above 9
$numOfTracks = 5;
 
function getTracks($username, $time, $lastfmFile, $numOfTracks) {
//this will be the local xml file written to your server
$myLocalFile = $username.'.xml';
//if the local xml file doesn't exist or if local xml file is older than the time set
if ((!file_exists($myLocalFile)) || (time()-filemtime($myLocalFile)>$time)) {
	//get the last.fm xml file and place it into the contents variable as a string
	$contents = @file_get_contents($lastfmFile);
	//open the local file or create it if it doesn't exist
	$temp = fopen($myLocalFile, "w");
	//write the contents of the lastfmFile to the local file
	fwrite($temp, $contents);
	//close the file
	fclose($temp);
}
//grab the local xml file and place it into the xml variable
$xml = @simplexml_load_file($myLocalFile);
//create an unordered list of the track name and artist from the local XML file
print "
<ul>";
	for ($t = 0; $t <= $numOfTracks; $t++) {
		print "\n
<li><a href=\"".$xml->track[$t]->url."\" target=\"_blank\">".$xml->track[$t]->name." - ".$xml->track[$t]->artist."</a></li>
 
";
	}
	print "</ul>
 
";
}
 
getTracks($username, $time, $lastfmFile, $numOfTracks);

It isn't the most efficient code, but it works!

I set the time to 300 seconds (5 minutes), it's around the average time it takes to listen to a song. This is to reduce server load and loading times; there's no point in checking for a new song every minute or two.

If you have any improvements on the script, let me know.
