omit a div if its null

I have a div that looks like this:

<div id="restinfoinn">
  <div id="resthead">Purpose</div>
  <div id="restcontstitle2"><?php echo开发者_运维百科 $row_pages_here['purpose']; ?></div>
</div>

I want it to be omitted if the value of purpose is empty/null. How can I do this?

<?php if (!empty($row_pages_here['purpose'])) : ?>
<div id="restinfoinn">
  <div id="resthead">Purpose</div>
  <div id="restcontstitle2"><?php echo $row_pages_here['purpose']; ?></div>
</div>
<?php endif; ?>

But i think it would be better to print the empty div and deal with the design in CSS

This is really basic. You just need to do an IF check on top.

<?php if (!empty($row_pages_here['purpose'])) : ?>
    <div id="restinfoinn">
      <div id="resthead">Purpose</div>
      <div id="restcontstitle2"><?php echo $row_pages_here['purpose']; ?></div>
    </div>
<?php endif;?>

Have a look at alternative control syntax and empty
