What are the best practices for handling file uploads in PHP, especially when dealing with arrays like $_FILES?

When handling file uploads in PHP, especially when dealing with arrays like $_FILES, it is important to properly validate and sanitize the uploaded files to prevent security vulnerabilities. Additionally, it is recommended to move the uploaded files to a secure location on the server and store the file paths in a database for easy retrieval. 

// Example code snippet for handling file uploads in PHP

// Check if file was uploaded without errors
if(isset($_FILES['file']) && $_FILES['file']['error'] == 0){
    $file_name = $_FILES['file']['name'];
    $file_size = $_FILES['file']['size'];
    $file_tmp = $_FILES['file']['tmp_name'];
    $file_type = $_FILES['file']['type'];
    
    // Move the uploaded file to a secure location
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
    
    // Store the file path in a database for easy retrieval
    $file_path = "uploads/" . $file_name;
    // Insert $file_path into database
}
