php - How to get only numbers from last parentheses?
one text
Solution:
You could use a regex to search for digits in parentheses, using a negative lookahead to assert that there are no more parentheses after that number:
$string = "Mixing group (3pcs) (350) ";
preg_match('/\((\d+)\)(?!.*\(.*\))/', $string, $matches);
echo $matches[1];
Output:
350
