echo out a php variable inside a class : <p>I'm trying to echo out a php variable inside a div like that <code>&lt;div class="kor $value"&gt;</code></p>

<pre><code> $value = get_theme_mod( 'ani', 'fadeIn' );
$output .= apply_filters( 'wal') ? '&lt;div class="kor' &lt;?php echo $value' "&gt;':'');
</code></pre>
