In what situations would it be beneficial to use a Unix timestamp as the image name when uploading images in PHP?

Using a Unix timestamp as the image name when uploading images in PHP can be beneficial when you want to ensure unique file names for each uploaded image. This approach helps prevent naming conflicts and makes it easier to organize and manage the uploaded images. 

// Generate a unique filename using a Unix timestamp
$timestamp = time();
$image_name = $timestamp . '_' . $_FILES['image']['name'];

// Upload the image with the unique filename
move_uploaded_file($_FILES['image']['tmp_name'], 'uploads/' . $image_name);
