PHP Version

This code uses Version 5 of PHP, not a lot of webservers run this. I just thought I'd add this comment as I took this code and hacked it and tried to slap it on my website - Scappy - (site / last.fm)

Description

I wanted a way of incorporating my latest tracks into another site, and an image was going to be far easier than SSI'ing the page itself. So, here I present the php code I wrote to generate an image.

Note that this requires PHP with GD and SimpleXML compiled in. I tried screwing around with transparency, but I didn't want to spend the time to really get it working. Perhaps someone else can improve on this.

Additionally, this is currently designed to use the Verdana TTF font. I just copied it out of my Windows font directory to the webserver. As an alternative, use the commented-out string function instead.

Call the PHP script

<?php include("http://example.com/script.php?user=myUserName&display=4"); ?>

The PHP script

<?php
function MDashedLine($image, $x0, $y0, $x1, $y1, $fg, $bg)
{
        $st = array($fg, $fg, $fg, $fg, $bg, $bg, $bg, $bg);
        ImageSetStyle($image, $st);
        ImageLine($image, $x0, $y0, $x1, $y1, IMG_COLOR_STYLED);
}


$user = $_GET['user'];
$display = $_GET['display'];

$buffer = 10;
$spacing = 15;
// I'd move this line down, just in case $display
// is less than the number of tracks
// there is info for. -- Joe
// $h = ($display * $spacing) + $buffer;
$w = 300;

$xml = file_get_contents("http://ws.audioscrobbler.com/1.0/user/" . $user ."/recenttracks.xml");

$sxml = simplexml_load_string($xml);

$i=0;

foreach ($sxml as $track) {
        $text[$i] .= $i+1 .". " . (string)$track->{"artist"} . " - " . (string)$track->{"name"};
        if (++$i == $display) break;
}
// Something like this:
$h = ( count($text)* $spacing) + $buffer;
