PHP entry level question
<p>I expect the output of "inside test finish" when loaded the index.php file instead I got nothing.</p>

<p>index.php:</p>

<pre><code>&lt;?php
@include_once('functions.php');
test();
echo "finish";
?&gt;
</code></pre>

<p>inside the <code>functions.php</code> there's a </p>

<pre><code>&lt;?php
function test()
{
  echo "inside test";
}
</code></pre>
