Question

Im trying to just get the count value using mysql_fetch_row but the echo is Array9, when I just want 9.

            <?php
          $result = mysql_query("SELECT * FROM `product_category` ORDER BY `product_category_name`");
          while($row = mysql_fetch_array($result)) {

              echo '
              <li  class="ui-shadow" data-count-theme="d">
              <a href="' . $row['product_category_ref_page'] . '.php" data-icon="arrow-r" data-iconpos="right">' . $row['product_category_name'] . '</a><span class="ui-li-count">' . 

                $number = mysql_fetch_row(mysql_query("SELECT COUNT(`category_id`) FROM `products_has_product_category` WHERE `category_id`=" . $row['product_category_id'] . ""));
                echo $number[0];

              '</span></li>';
          }

        ?>

Would appreciate any help!

No need for a nested query. Can be done with a JOIN, something like as follows:-

    SELECT a.*, COUNT(b.category_id) AS CatCount
    FROM `product_category` a
    LEFT OUTER JOIN `products_has_product_category` b
    ON a.product_category_id = b.category_id
GROUP BY a.id, a.someothercolumn, a.etc
