PHP file upload not working

Question

I'm trying to upload files to my server but it doesn't work at all. Here is test code:

<?php
echo count($_FILES['upload']['name']);
?>

<!DOCTYPE html>
<html>
<body>

<form action="" method="POST" enctype="multipart/form-data">
    <input name="upload[]" type="file" accept=".mp3" multiple="multiple" />
    <br>
    <input type="submit" value="Upload">
</form>

</body>
</html>

It always prints 0, file upload is enabled on my server.

<input name="upload" type="file" accept=".mp3" multiple="multiple" /> remove [] OR var_dump($_FILES['upload']) for multiple files — Jeremy

if you make echo count($_FILES['upload']) you'll obtain the correct result. It will be an array of elements with only one element. As @Jeremy suggest, remove the array [] notation to avoid send array instead of propper file (at least if you don't have to send multiple files at once) — Marcos Pérez Gude

I just tested the code on my live server and it works, time to reinstall wamp.... — user47823

The problem is that you're not counting the $_FILES['upload'].

Simple fix for your problem
Use:

echo count($_FILES['upload']);

Instead of:

echo count($_FILES['upload']['name']);

Edit: Remove [] from the input's name.

Still not working, I think the code isn't the problem since it works on live server.

@user47823 I fixed one thing in the code. Try reinstalling your apache server's software (eg. Wamp), then look for the Apache config if it's still not working.
