how can I use xpath with for instead of foreach - php

Question

I want to scrape a website that has 3 levels of scraping. firs I get all pages, then in each page, I get image, title, url that redirects me to a unique page which contains more info like description , date ,... . so if I use foreach it gives me the false results and if I use for instead of foreach it returns just one object. how can I handle if(use for instead of foreach);
