What are the potential security risks associated with allowing music producers to upload their own instrumental tracks on a PHP-based music shop website?

Allowing music producers to upload their own instrumental tracks on a PHP-based music shop website can pose security risks such as potential malware or malicious scripts being uploaded to the server, leading to possible data breaches or unauthorized access. To mitigate these risks, it is essential to implement strict file type validation, limit file size, and use server-side validation to ensure that only safe and authorized files are uploaded. 

// Example PHP code snippet for file upload with security measures

// Define allowed file types
$allowed_types = array('mp3', 'wav');

// Define max file size
$max_size = 5242880; // 5MB

// Check if file type is allowed
$file_extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
if (!in_array($file_extension, $allowed_types)) {
    // Handle error - file type not allowed
}

// Check file size
if ($_FILES['file']['size'] > $max_size) {
    // Handle error - file size exceeds limit
}

// Perform server-side validation and further processing
