What are the advantages and disadvantages of including the code for image downloading within the index.php file?

When including the code for image downloading within the index.php file, the advantage is that it keeps all related functionalities in one place for easier management. However, the disadvantage is that it can make the index.php file bloated and harder to maintain, especially if there are multiple functionalities included. It's generally recommended to separate concerns and keep the code modular for better organization and scalability.

// Separate the image downloading functionality into a separate file and include it in index.php

// image_downloader.php
<?php

// Code for image downloading functionality

?>

// index.php
<?php

// Other index.php code

include 'image_downloader.php';

?>
