Are there any best practices for handling file uploads and database storage in PHP?

When handling file uploads in PHP, it's important to validate the file type, size, and ensure secure storage in the database. One best practice is to move the uploaded file to a secure directory on the server and store the file path in the database. This helps prevent direct access to the uploaded files and ensures better control over file management. 

// Handle file upload
$uploadDir = 'uploads/';
$uploadFile = $uploadDir . basename($_FILES['file']['name']);

if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadFile)) {
    // File uploaded successfully, store file path in database
    $filePath = $uploadFile;
    // Insert $filePath into database
} else {
    echo "Error uploading file.";
}
