Converting spotify json file to html - php

Question

I am trying to convert a spotify json file to a html table. However this json file is a bit complex. I am making a mistake somewhere, but can't find out what I am doing wrong. What is the proper code?
<?php
$spotifylist = "http://spotifycharts.com/api/?type=regional&country=nl&recurrence=daily&date=latest&limit=200";
$contents = file_get_contents($spotifylist);
$decoded = json_decode($contents,true);
$results = $decoded->entries[0]->items;
echo "<table class='chart'> <thead><tr class='row2'><th class='dw'></th><th class='song'>Artiest</th><th class='song'>Titel</th></tr></thead><tbody>";
foreach($results as $entry){
$artist = $entry->track->artists->name;
$name = $entry->track->name;
$x = $entry + 1;
$color = ($x%2 == 0)? 'row2': 'row1';
echo "<tr class='$color'>";
echo "<td class='dw'>". $x ."</td>";
echo "<td class='song'>". $artist ."</td>";
echo "<td class='song'>". $name ."</td>";
echo "</tr>";
}
echo "</tbody></table>";
?>

Your code is a bit confused. I've cleaned it up a little bit in order that it can work, but I think you need to look at it more closely – it pulls very precise pieces of data out of the feed, which might not be safe.
Working code below:
<?php
$spotifylist = "http://spotifycharts.com/api/?type=regional&country=nl&recurrence=daily&date=latest&limit=200";
$contents = file_get_contents($spotifylist);
$decoded = json_decode($contents);
$results = $decoded->entries->items;
echo "<table class='chart'> <thead><tr class='row2'><th class='dw'></th><th class='song'>Artiest</th><th class='song'>Titel</th></tr></thead><tbody>";
$counter = 0;
foreach($results as $entry){
++$counter;
$artist = (string)$entry->track->artists[0]->name;
$name = $entry->track->album->name;
$color = ($counter % 2 == 0) ? 'row2': 'row1';
echo "<tr class='$color'>";
echo "<td class='dw'>$counter</td>";
echo "<td class='song'>". $artist ."</td>";
echo "<td class='song'>". $name ."</td>";
echo "</tr>";
}
echo "</tbody></table>";
?>
