Inside foreach loop the valid array is $artist_name so
$artist_name->artist_name will work but $album_title->album_title and
$release_date->release_date will not work because $album_title and
$release_date are not arrays.
Check http://www.php.net/manual/en/control-structures.foreach.php for
more info.
Check for print_r also.
http://gr2.php.net/manual/en/function.print-r.php
If you want to have better code, you have to check if $results is array
and has values.
if (is_array($results) && count($results))
{
// array has values
foreach ($results as $res)
{
// code here
}
}
else
{
// array is empty.
// code here
}
