php empty() or isset() checking more than 1 variable
<p>I use </p>

<pre><code>if(!empty($_POST['login'])){
}
</code></pre>

<p>for checking that login is file is filled, it work when I checking 1 variable, but not working when I use  </p>

<pre><code>if(!empty($_POST['login'],$_POST['password'] )){
}
</code></pre>

<p>how to check 2 variables, I see that isset() too support only 1 variable </p>
