Question

I have three variables ($var, $var2 & $var3) and I want it to output when they have value.

For example, if $var = "Data"; then:

<ul>
<li>Data</li>
</ul>

And if any of the other variables has value then:

<ul>
<li>Data</li>
<li>Data2</li>
</ul>

Or

<ul>
<li>Data</li>
<li>Data3</li>
</ul>

<ul>
<li>Data</li>
<li>Data3</li>
<li>Data2</li>
</ul>

I am not exactly sure how to create this and with what method considering everybody has different ways of doing their php code. Does anybody know how I can create this?

Also: I use http://writecodeonline.com/php/ when testing certain php codes.

Answer 1

<ul>
    <?php foreach (array($var1, $var2, $var3) as $var) : ?>
        <?php if (!empty($var)) : ?>
            <li><?php echo $var; ?></li>
        <?php endif; ?>
    <?php endforeach; ?>
</ul>

You can see the output here on writecodeonline.com.

Or maybe you prefer this:

<ul>
    <?php
    foreach (array($var1, $var2, $var3) as $var) {
        if (!empty($var)) {
            echo '<li>' . $var . '</li>';
        }
    }
    ?>
</ul>

(it doesn’t matter really, just use whatever you think looks better)
