Why should we use <?php for embedding php code?
<p>I once posted a question here with php code embedded using <code>&lt;?</code>.
Someone told me I should NOT do that and I should use <code>&lt;?php</code></p>

<p>The person did not tell me why it is so. Can someone please explain why it is unsafe to use <code>&lt;?</code>?</p>
