How can i create a function that takes un-assigned variable in PHP
<p>I'm trying to make a function that takes a variable whether it was set or not,</p>

<p>like the function isset()</p>

<pre><code>//we have this array
$array  = array();
isset($array["test"]);//this one is valid 
myFunc($array["test"]);//this one is not valid 
</code></pre>

<p>how can i let my function take not set variables? </p>
