PHP curly string syntax question
<p>I'm running PHP 5.3.0. I've found that the curly string syntax only works when the first character of the expression is <code>$</code>. Is there a way to include other types of expressions (function calls, etc)?</p>

<p>Trivial example:</p>

<pre><code>&lt;?php
$x = '05';
echo "{$x}"; // works as expected
echo "{intval($x)}"; // hoped for "5", got "{intval(05)}"
</code></pre>
