Why does preg_match_all return an empty array?

Question

PHP

Good evening, I'm trying to write a parser, I take the page through cURL (everything is fine, the page is completely taken away)
then I want to pull out all the links to the news using a regular expression, here's the code:

preg_match_all("/<div class=\"article\">.*href=\"(.*)\">/U", $html, $links);

I wrote the regex on the site https://regex101.com, the regex works there, but in the code it outputs an empty array.

Answer 1

that's all, I deduced, it was necessary to push an array into a variable that gives preg_match_all
