As part of the New Years Resolutions I didn’t make.<\/p>\n

I’m updating my blog with some Code Snippets!<\/p>\n

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

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

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.<\/p>\n

So went back to my curl method.<\/p>\n

Tidyied it up and got it down to a few less lines.<\/p>\n

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)<\/p>\n

$curl = new curl();\r\n\r\n$data = array(\r\n\t'title'\t\t=> 'Showdown',\r\n\t'artist'\t=> 'Pendulum',\r\n\t'release'\t=> 'In Silico',\r\n\t'duration'\t=> 327784,\r\n\/\/\t'tracknumber'\t=> 0,\r\n\/\/\t'count'\t\t=> 10,\r\n\/\/\t'releasetype'\t=> '',\r\n\r\n\t'limit'\t\t=> 25,\r\n\t'limit'\t\t=> 1,\r\n);\r\n$target = 'http:\/\/musicbrainz.org\/ws\/1\/track\/?type=xml';\r\nforeach ($data as $ref => $dat) {\r\n\t$target .= '&' . $ref . '=' . urlencode($dat);\r\n}\r\n\r\n                                $curl->target($target);\r\n                                $curl->runit();\r\n                                $mb = $curl->bodyarray['metadata'];\r\n\r\nif (isset($mb['track-list'])) {\r\n\t$mb = $mb['track-list'];\r\n\r\n\tif (isset($mb['track']['0'])) {\r\n\t\t$mb = $mb['track'];\r\n\t\t$artist_id = $mb['0']['artist_attr']['id'];\r\n\t\t$song_id = $mb['0_attr']['id'];\r\n\t} else {\r\n\t\t$artist_id = $mb['track']['artist_attr']['id'];\r\n\t\t$song_id = $mb['track_attr']['id'];\r\n\t}\r\n} else {\r\n\t\/\/ no data\r\n}\r\n\r\necho \"\\n\" . $artist_id .

Where new curl() just calls my Curl Class.<\/p>\n
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.<\/p>\n
The result is in $curl->body, or exploded nicely as an array in $curl->bodyarray. I’ll post about my curl later! As well as some other Carlyon_CMS stuff.<\/p>\n
So thats a quick rough and ready way to get a artist and song ID from MusicBraiz.<\/p>\n
Its worth noting that since my limit is st to 1.<\/p>\n
The first option of if (isset($mb[‘track’][‘0’]) is entirely redundant, as that only triggers when mb returns more than 1 result.<\/p>\n
(I only just added limit before writing this post, which is where I decided to write this post)<\/p>\n
