如何在PHP中为歌曲添加元数据标题，艺术家等？

I have created a Youtube to mp3 script with PHP. I would like to add the ability to add metadata of the title, artists, album, etc. I have created a test PHP script, using the id3_set_tag() function to add metadata to an MP3 but when I load the page it is blank and the file remains untouched.

<?php
$data = array(
              "title" => "Re:Start",
              "artist" => "Re:\Legion",
              "comment" => "A nice track"
             );
$result = id3_set_tag( "Test.mp3", $data, ID3_V1_0 );
if ($result === true) {
    echo "Tag successfully updated
";
}
?>

Here are the Apache/PHP logs:

[Mon Jun 11 17:54:39.197984 2018] [php7:error] [pid 1458] [client 127.0.0.1:51864] PHP Fatal error: Uncaught Error: Call to undefined function id3_set_tag() in /Library/WebServer/Documents/index.php:7 Stack trace: #0 {main} thrown in /Library/WebServer/Documents/index.php on line 7

Specs: Apache

PHP 7

macOS High Sierra

So my question is: How do I add song metadata to a MP3 file with PHP on Mac?
