Creating a reference to variable directly from string (without switch statement)
<p>I know the title is not very clear so here it's in code:</p>

<pre><code>function output($selector){
    $one = 1;
    $two = 2;
    $there = 3;

    return ? //should return 1 without if or switch statement
}


echo output('one');
</code></pre>

<p>If this is possible, how?</p>
