PHP parser. How to make a function to extract text from a given link?

Question

PHP

I am making a PHP parser that should copy all publications from the site and display this information on my site (this is not content theft, I agreed with the site owner)!
I have already written a code that copies the list of publications on the main page (title, photo and short text), now I need to parse the content of each publication, for this I started to parse links to all publications (on the main page of the site). Now I need to write a function that will parse the content of each post for these links. Please show with an example how to parse the text that is inside each link!

There is a good library simple_html_dom read the documentation for a lot of information on it.
Example of my code:

$html = new simple_html_dom();
            $html->load_file($_GET['go']);
            $name = $html->find('h2');
            $description = $html->find('div');    
            $video = $html->find('iframe[width=770]'); 
            $video = $text = preg_replace('/.*\/embed\/(.+)/i', 'https://www.youtube.com/watch?v=$1', $video[0]->src) ;
            $description = replace($description[$_GET['id']]->xmltext) ;
            $description = preg_replace('/<!.*>.*/is', '', $description) ;
            $spoilers = $html->find('div.uSpoilerText') ;
            $spoiler = '' ;
            foreach($spoilers AS $k => $post){
                $text = replace($post->xmltext) ;
                preg_match_all("/<!--usn\(\=(.*)\)-->/i", $text, $title);
                $text = preg_replace('/<!--ust-->/i', '', $text) ;
                $text = preg_replace('/<!--usn\(\=(.*)\)-->/i', '', $text) ;
                $text = preg_replace('/<!--\/ust-->/i', '[/spoiler]', $text) ;
                    //echo $k . ' -> ' . $post->xmltext . '<hr /><br />' ;
                $spoiler .= '[spoiler title="' . $title[1][0] . '"]' . $text . "\n\n" ;
            }
            
            $description = '[b]Название:[/b] [u]' . $name[0]->plaintext . '[/u] скачать торрент' . $description . $spoiler . $video ;
            //$file->meta_description = $title . ' скачать с торрента бесплатно в хорошем качестве' ; 
            //$file->runame = $name[0]->plaintext ;
            $file->description = $description ;
        }
        $groups = groups::load_ini(); // загружаем массив групп

        $form = new form(new url);
        $form->text('name', __('Название файла') . ' *', isset($name[0]->plaintext) ? $name[0]->plaintext : $file->runame);
        $form->text('link_name', __('Доступен по адресу'), $file->name);
        $form->textarea('description', __('Описание'), $file->description);
        $form->textarea('description_small', __('Краткое описание'), $file->description_small);

Pay no attention to $form.
An example of a page that I parse https://manytorrents.pro/load/films/boeviki/chudo_...
The script has not been used for a long time, so this particular example may not work for this page

Well, everything is great.
First you get a list of links that you want to parse.
You drive this business in an array. And then in the array you go through each link and parse what you need.
