Heard of SQL Injection[^]?
You should use prepared statement, for example:

$search_query = '%'.$_GET['user_query'].'%';

// Create a prepared statement
if($stmt = $mysqli -> prepare("SELECT * FROM product WHERE title LIKE ?")) {

   // Bind parameter
   $stmt -> bind_param("s", $search_query);

   $stmt -> execute();

   $run_pro = $stmt->get_result();

   while ($row = $run_pro->fetch_array(MYSQLI_ASSOC)) {
      $pro_id = $row['id'];
      // other code
   }
}
