You you are using this package: https://github.com/fxb/php-last.fm-api
You might have forgotten to autoload api classes:
require __DIR__ . "/src/lastfm.api.php";
Or you can add it to composer.json, as an example:
"autoload": {
"files": [
"/var/www/yourproject/libraries/lastfm.api/src"
],
},
And execute:
composer dump-autoload
EDIT:
You are using one package and the example from another one. There is no Album class in the package you are using, here is a full example of it:
<?php
// Include the API
require '../../lastfmapi/lastfmapi.php';
// Get the session auth data
$file = fopen('../auth.txt', 'r');
// Put the auth data into an array
$authVars = array(
'apiKey' => trim(fgets($file)),
'secret' => trim(fgets($file)),
'username' => trim(fgets($file)),
'sessionKey' => trim(fgets($file)),
'subscriber' => trim(fgets($file))
);
$config = array(
'enabled' => true,
'path' => '../../lastfmapi/',
'cache_length' => 1800
);
// Pass the array to the auth class to eturn a valid auth
$auth = new lastfmApiAuth('setsession', $authVars);
// Call for the album package class with auth data
$apiClass = new lastfmApi();
$albumClass = $apiClass->getPackage($auth, 'album', $config);
// Setup the variables
$methodVars = array(
'artist' => 'Green day',
'album' => 'Dookie'
);
if ( $album = $albumClass->getInfo($methodVars) ) {
// Success
echo '<b>Data Returned</b>';
echo '<pre>';
print_r($album);
echo '</pre>';
}
else {
// Error
die('<b>Error '.$albumClass->error['code'].' - </b><i>'.$albumClass->error['desc'].'</i>');
}
?>
