How to upload .mp3 files with PHP?

Question

<form enctype="multipart/form-data">

<input type="file" name="mp3" />
<input type="submit" />
</form>

I tried the above,and found var_dump($_FILES); is always empty.

It only works when you upload text files or images.

UPDATE

I added method="POST" and it works.Why is POST necessary here?

Answer 1

Did you specify the form method to be POST explicitly and try?
