Long Time Since I blogged

A General Update….

Again, its been a while. Things have been pretty busy.

Currently I just fixed the LSRfm.com Podcasts, they were downloading a minute or two of audio the PHP was dying, FAST CGI php5 was being ghey.

So after a quick chat with Dreamhost over live chat, my script now rather than munch the file, just passes it off to a http location, less of a memory muncher too.

SRAchart is its usual self, tho we did get a full house of Charts last week, (well near enough), Ellie Goulding and Owl City are dominating, and Glee Started Charting too.

(Yes I am a Glee Fan)

Handed in the Motion Graphics Brief.

So Uni Wise I just need to sit down and code code code, both for Project 2 (ala 360gaming.net enhancements), and start planning and researching what I need for project 2.

And start writing an essay for Futures and Strategies, fun times.

I’ve not had any spare time to play Halo, tho the Reach Beta has been announced! Hurrah!

Now I must get back to coding stuff for LSRfm.com fixed the Jukebox, now to do the music db, tho I do have a nice IRC bot sat in the new LSRfm.com Chatbox

Also <3 jQuery....

Curl, MusicBrainz and PHP

A quick block of PHP to fetch MusicBrainz ID for a song and artist based on Song Data.

As part of the New Years Resolutions I didn’t make.

I’m updating my blog with some Code Snippets!

Been fiddling about with my PHP powered Jukebox that plays out on LSRfm.com (Leeds Student Radio) Overnight, and there is a need for a bulk track adder.

So, I’ve been tidying up the MusicBrainz Data Fetcher, as well as fiddling with PHP and getting ID3 tags from Files. But thats a different blog post.

Essentially there is a (new-ish non updated recently) PHP Library for the interaction with MusicBrainz, (A music database), recently found that (this morning its rubbish), but of no good.

So went back to my curl method.

Tidyied it up and got it down to a few less lines.

Essentially for a given track, the PHP extracts the ID3 tags, and then passes it to this function: (its needs making into a function btw :-P)

$curl = new curl();

$data = array(
	'title'		=> 'Showdown',
	'artist'	=> 'Pendulum',
	'release'	=> 'In Silico',
	'duration'	=> 327784,
//	'tracknumber'	=> 0,
//	'count'		=> 10,
//	'releasetype'	=> '',

	'limit'		=> 25,
	'limit'		=> 1,
);
$target = 'http://musicbrainz.org/ws/1/track/?type=xml';
foreach ($data as $ref => $dat) {
	$target .= '&' . $ref . '=' . urlencode($dat);
}

                                $curl->target($target);
                                $curl->runit();
                                $mb = $curl->bodyarray['metadata'];

if (isset($mb['track-list'])) {
	$mb = $mb['track-list'];

	if (isset($mb['track']['0'])) {
		$mb = $mb['track'];
		$artist_id = $mb['0']['artist_attr']['id'];
		$song_id = $mb['0_attr']['id'];
	} else {
		$artist_id = $mb['track']['artist_attr']['id'];
		$song_id = $mb['track_attr']['id'];
	}
} else {
	// no data
}

echo "\n" . $artist_id . ' ' . $song_id;

Where new curl() just calls my Curl Class.

I’m sure you have your own ways of doing curl, but mine just sets the target with $curl->target and curlexec() with $curl->runit.

The result is in $curl->body, or exploded nicely as an array in $curl->bodyarray. I’ll post about my curl later! As well as some other Carlyon_CMS stuff.

So thats a quick rough and ready way to get a artist and song ID from MusicBraiz.

Its worth noting that since my limit is st to 1.

The first option of if (isset($mb[‘track’][‘0’]) is entirely redundant, as that only triggers when mb returns more than 1 result.

(I only just added limit before writing this post, which is where I decided to write this post)
