写入标签后如何保存文件？

Question

我正在尝试使用getID3库更改mp3文件的曲目详细信息，然后将其保存到目录中。

写入标签后如何保存文件？

<?php
$remotefilename = 'http://musicbaap.com/public/music/Same-Beef-[Original]-Sidhu-Moose-Wala.mp3';
if ($fp_remote = fopen($remotefilename, 'rb')) {
    $localtempfilename = tempnam('/tmp', 'getID3');
    if ($fp_local = fopen($localtempfilename, 'wb')) {
        while ($buffer = fread($fp_remote, 8192)) {
            fwrite($fp_local, $buffer);
        }
        fclose($fp_local); 
        $getID3 = new \getID3;  
        $tagwriter = new \getid3_writetags;
        $tagwriter->filename = $localtempfilename;
        $tagwriter->tagformats = array('id3v1', 'id3v2.3'); 
        // set various options (optional)
        $tagwriter->overwrite_tags = true;
        $getID3->encoding =  'UTF-8';
        $tagwriter->tag_encoding = 'UTF-8';
        $tagwriter->remove_other_tags = true;

        // populate data array
        $TagData['title'][] = 'My Song';
        $TagData['artist'][] = 'The Artist';
        $TagData['album'][] = 'Greatest Hits';
        $TagData['year'][] = '2004';  
        $tagwriter->tag_data = $TagData; 
        // write tags
        if ($tagwriter->WriteTags()) {
            echo 'Successfully wrote tags<br>'; 
            if (!empty($tagwriter->warnings)) {
                echo 'There were some warnings:<br>'.implode('<br><br>', $tagwriter->warnings);
            }
        } else {
            echo 'Failed to write tags!<br>'.implode('<br><br>', $tagwriter->errors);
        } 
        // dd($tagwriter);
    }
    fclose($fp_remote);
}

该文件具有在调用方法后写入的标签。

$localtempfilename = tempnam('/tmp', 'getID3');

在这里将文件放置在计算机上，这也是“保存”文件的地方。 完成所需的所有操作后，更改将保存到该文件中。
