How to insert dynamic content into posts

I'm currently using this plugin which creates batches of posts from uploaded images

I'm also using this code here to generate the default content for every new post

add_filter( 'afip_new_post_content', 'diww_default_post_content' );
function diww_default_post_content() {
$content = "<iframe src=></iframe>";
return $content;

Now I have a php array of URL's which I want to insert into the src for each post. Is it possible via some loop or sequential manner insert each URL into each post sequentially?


URL[0] -> Post[0]
URL[1] -> Post[1]
URL[2] -> Post[2]

and so on.
