return multiple values (variables) with PHP

Question

hello there i am working on a function which should return a database result set AND the time it took the query to retrieve the data. Works good but i don't know how to return the time and the result set and make them available in the view. Thanks for help.

My code looks like this:

public function getNumResults($term) {

   /* Count query Execution */
   $starttime = microtime(true);

   $query = $this->con->prepare("SELECT COUNT(*) as total
       FROM sites WHERE title LIKE :term
       OR url LIKE :term
       OR keywords LIKE :term
       OR description LIKE :term");

   $endtime = microtime(true);

   /* Calculates total time taken */
   $duration = $endtime - $starttime;

   $searchTerm = "%". $term . "%";
   $query->bindParam(":term", $searchTerm);
   $query->execute();

   $row = $query->fetch(PDO::FETCH_ASSOC);

   return $row["total"];

}

In the view i return the result set like so:

<div class="mainResultSection">
        <?php
          $resultsProvider = new SearchResultsProvider($con);
          $numResults = $resultsProvider->getNumResults($term);
          /* Not working */
          $timeResults = $resultsProvider->getNumResults($term)->duration;
          echo "<p class='resultsCount'>$numResults results found. In $timeResults <p>";
        ?>
      </div>

Too inexperienced. I went with another function to get the duration. But the other answers given helped a lot. Thanks, here the final code working:

/* Time to get results */
public function getTimeResult($term){
   $query = $this->con->prepare("SELECT COUNT(*) as total
        FROM sites WHERE title LIKE :term
        OR url LIKE :term
        OR keywords LIKE :term
        OR description LIKE :term"
   );

   $searchTerm = "%". $term . "%";
   $query->bindParam(":term", $searchTerm);

   $starttime = microtime(true);
   $query->execute();
   $endtime = microtime(true);

   /* Calculates total time taken */
   $duration = $endtime - $starttime;

   return $duration;
}
