last.fmから最新の再生履歴を配列として取得するphpスクリプト

last.fm から自分の再生履歴を配列として取得するphpスクリプトのサンプルを以下に示す。

<?php

// --
// VERSION CHECK
// --
if( version_compare(phpversion(), '5.0', '<') ) {
    echo "本スクリプトはPHPのVersion5.0以降でのみ動作します\n";
    exit;
}

// --
// LOAD XML
// --
$_lastfmName = 'mahata';
$_targetUrl = "http://ws.audioscrobbler.com/1.0/user/{$_lastfmName}/recenttracks.xml";
$_xmlObj = simplexml_load_file($_targetUrl);

// --
// MAKE ARRAY
// --
$_playList = array();
foreach( $_xmlObj as $_xmlObj_ ) {
    $_tArray = array();
    $_tArray['artist']  = (string)$_xmlObj_->artist;
    $_tArray['name']    = (string)$_xmlObj_->name;
    $_tArray['album']   = (string)$_xmlObj_->album;
    $_tArray['date']    = date('Y/m/d H:i:s', (int)strtotime($_xmlObj_->date));

    $_playList[] = $_tArray;
}

// --
// DUMP ARRAY
// --
print_r( $_playList );

?>

ここで、$_lastfmNameに任意のIDを設定すればよい。
実行結果は次のようになる。
