How to allow to receive site content through iframe?

Question

PHP

At first I tested everything on localhost, but now I transferred the images to one hosting, and the site to another. When a file is loaded, its name is placed in an iframe and the site needs to extract it, but the browser does not allow it. Can you somehow allow access to the site through the iframe?

Answer 1

CORS

Answer 2

I did such a thing like this:
t = file_get_contents(" www.intagme.com/... ");
$document = new DOMDocument();
$document->loadHTML($t);
foreach($document->getElementsByTagName('img') as $img)
{
$src []= $img->getAttribute('src');
}
Pulled out pictures, more precisely src of pictures and after where it is necessary - interposed.
In general, as far as I know, it is forbidden to access the iframe by the browser's security policy, and even more so if it is not within the same domain...
