What are the best practices for handling multiple file uploads in PHP forms?

When handling multiple file uploads in PHP forms, it is important to properly iterate through the files array and handle each file individually. This can be done by using a foreach loop to loop through the $_FILES array and process each file one by one. Additionally, make sure to validate the file types, sizes, and any other necessary requirements before moving or saving the files. 

// Example PHP code snippet for handling multiple file uploads in a form

if(isset($_FILES['files'])){
    $errors= array();
    
    foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
        $file_name = $_FILES['files']['name'][$key];
        $file_size = $_FILES['files']['size'][$key];
        $file_tmp = $_FILES['files']['tmp_name'][$key];
        $file_type = $_FILES['files']['type'][$key];
        
        // Add validation logic here
        
        if(empty($errors)==true){
            move_uploaded_file($file_tmp,"uploads/".$file_name);
        }else{
            print_r($errors);
        }
    }
}
