I need to return some search results "ex: Digital Agency" from the first page of Google using preg_match + Regex, but it is not returning all 10 values in the array, only the first. How do I resolve?

Ex:

$document = file_get_contents('https://www.google.com/search?q=Ag%C3%AAncia+Digital');

preg_match_all('/<li class=\"g\">([^`]*?)<\/li>/', $document, $matches);

print_r($matches);

  • I tested your code here, came an array with two keys and 10 elements (html) in each but I had to use the option to display browser source code.

When syntactically parsing the HTML of a page with Regular Expressions, unfortunately being specific can be a problem.

In such cases you should capture everything that is within a specific content delimiter, in your case the <li></li>. And because of the ? in your group you undo quantifier’s greed *.

Literally, it’s like you’re saying: Anything that’s not a backtick, in any amount, but if you don’t have any, that’s fine too.

So much so that it was enough to remove the question mark and all the other results appeared.
