keys and values without quotes in an Array?
<p>Help me understand this code :</p>

<pre><code>Array
(
    [font-family] =&gt; font-family: 'Abel', sans-serif;
    [font-name] =&gt; Abel
    [css-name] =&gt; Abel
)
</code></pre>

<p>from : <a href="http://phat-reaction.com/googlefonts.php" rel="nofollow">http://phat-reaction.com/googlefonts.php</a> .</p>

<p>Why there are no quotes around keys and values ? Is this valid php code ?</p>
