Grab last listened last.fm track from rss feed

[maczaaron]

I am trying to make an image with php that overlays my last played last.fm track (accessible via the rss feed://ws.audioscrobbler.com/1.0/user/theusernamehere/recenttracks.rss) onto a static image, background.

 

I am very new to php, and have a starting point:

<?php
$myimage = imagecreatefrompng ( "mytemplate.png" );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
imagestring( $my_img, 4, 30, 25, "thesitewizard.com",
  $text_colour );
imagesetthickness ( $my_img, 5 );

header( "Content-type: image/png" );
imagepng( $my_img );
imagecolordeallocate( $text_color );
imagedestroy( $my_img );
?>

 

Now, instead of the text there right now, how can I make it grab the last played track from that rss feed and display it on the image (in the imagestring)?

 

Thanks for any help.

You will need to open the RSS feed and read what the last value is. I recommend checking out Handling XML data over in the tutorials section.

By the way, will this use a lot of bandwidth on my server? Picturing that the php gets requested 100+ times a day.

Depends on your definition of 'alot of bandwidth'. I doubt the size of the image should be much more than a few kilobytes, which gives a total transfer of a few hundred kilobytes.

Well, because I have 15 GB bandwidth available a month (already using about 12 a month, so that leaves <3 GB a month for this). That means 100 MB a day, so I guess no problem.
