copied!<p>That code could be looked like this:</p> <pre><code><?php include('connect.php'); $result = mysql_query("SELECT DISTINCT category FROM categories") or die(mysql_error()); while ($row = mysql_fetch_array($result)) { echo "<div>"; echo "<h2 class='title'>" . $row['category'] . "</h2>"; echo "<p>"; echo "<ul class='links'>"; $result1 = mysql_query("SELECT * FROM categories WHERE category = {$row['category']}") or die (mysql_error()); while ($row1 = mysql_fetch_array($result1)) { echo "<li><a href='" . $row1['sub_category_href'] . " target='_top'>" . $row1['sub_category'] . "</a></li>"; } echo "</ul>"; echo "</p>"; echo "</div>"; } ?> </code></pre> <p>But I suggest you to optimize in this manner:</p> <pre><code><?php include('connect.php'); $result = mysql_query("SELECT * FROM categories") or die(mysql_error()); $cats = array(); while ($row = mysql_fetch_array($result)) { $category = $row['category']; $sub_category = $row['sub_category']; $sub_category_href = $row['sub_category_href']; $cat_hrefs[$category][$sub_category] = $sub_category_href; } foreach ($cat_hrefs as $category => $sub_category_hrefs) { echo "<div>"; echo "<h2 class='title'>" . $category . "</h2>"; echo "<p>"; echo "<ul class='links'>"; foreach ($sub_category_hrefs as $sub_category => $sub_category_href) { echo "<li><a href='" . $sub_category_href . " target='_top'>" . $sub_category . "</a></li>"; } echo "</ul>"; echo "</p>"; echo "</div>"; } ?> </code></pre> <p>You do not need to make three queries, because you can do it in one query, which is more optimal.</p>

Querying!
