Linking up the correct quotation marks

echo "<td class='left'><a href='member.php?id=<?php echo $dnn['id']; ?>'>$username<?php echo htmlentities($dnn['username'], ENT_QUOTES, 'UTF-8'); ?></a></td>";

Remove the PHP tags within your string. Variables are expanded within double quotes. However more complicated variables, such as associative arrays need to be wrapped in braces

Also functions cannot be called within strings, so you need to use the concatenation operator.

echo "<td class='left'><a href='member.php?id={$dnn['id']}'>$username".htmlentities($dnn['username'], ENT_QUOTES, 'UTF-8')."</a></td>";
