How to read mp3 metadata in php

Question

My problem is simple, i need to read/write metadada from/into a mp3 file from a php script, but I can't find any reliable sorce of information. I'm over a week searching for answers but no real solution.

To explain my self a little better, I need to upload a mp3 file that has metadata attached, read this data and store in my database. After thar initial load, any new mp3 files that will be sent, will not have any metadata, and my system must insert some data into it, like track name, author, and a few others.

I can't find the a working solution for this read/write metadata anywhere, just some offline docs and outdated information.

Answer 1

If your path to your mp3 file is for example "/var/lib/my_mixtape.mp3", then give the code below a try:

$mp3FileLocation = "/var/lib/my_mixtape.mp3";
$metaData = id3_get_tag($mp3FileLocation);

// Fetch the necessary information from the $meta

For further reference, checkout the PHP documentation on the id3 function.
