Changing the description of a MP3 file?

Question

I am currently using simple_html_dom to parse some MP3 files from another website, and store them onto my own server. However I've noticed that some of them contain a tag which indicates the location they originated from within the comment portion of the ID3 properties .

I need to make this website, say my own websites name. However, the only solution that I've found to doing this with PHP is beyond complicated using something called GETID3.php You can view the github link by clicking the name.

I don't really understand the documentation can someone help me find an easier way of doing this please?

Here's the part of my code that matters, I guess.

$mp3title = ''.$thetitle.' - Oursite.com';
file_put_contents($DPATH.'/temp/'.$mp3title.'.mp3',file_get_contents($filepath));
$file = $DPATH.'/temp/'.$mp3title.'.mp3';

Provided you're not interested in also updating the image of the file, you can look into just using something simple like the default php function id3_set_tag however for more complex usages like updating the artwork then you're going to have to use the library you mentioned before.

$data = array(
    "title" => "Re:Start",
    "artist" => "Re:\Legion",
    "comment" => "YourWebsiteName.com"
);

$result = id3_set_tag($DPATH.'/temp/'.$mp3title.'.mp3', $data, ID3_V1_0 );
if ($result === true) {
    echo "Tag successfully updated\n";
}
