How can the process of uploading and processing multiple images be optimized for efficiency in PHP?

To optimize the process of uploading and processing multiple images in PHP, you can use a loop to iterate through each uploaded image and handle them individually. This approach allows you to process each image separately, reducing the load on the server and improving overall efficiency. 

// Loop through each uploaded file
foreach($_FILES['images']['tmp_name'] as $key => $tmp_name){
    $file_name = $_FILES['images']['name'][$key];
    $file_tmp = $_FILES['images']['tmp_name'][$key];
    
    // Process each image here (e.g. move to a specific directory, resize, etc.)
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
}
