Shortcut for checking if all $_POST fields are filled in php
<p>I know that I can check if the superglobal $_POST is empty or not by using </p>

<pre><code>empty / isset
</code></pre>

<p>However, I have many fields here. Is there any shortcut to check if all fields are filled? Instead of doing</p>

<pre><code>if (!empty($_POST['a']) || !empty($_POST['b']) || !empty($_POST['c']) || !empty($_POST['d']).... ad nauseum)
</code></pre>

<p>Thanks in advance!</p>
