Function that change args with php? 
<p>I dont know what we call this, but it will be something like this</p>

<pre><code>$args = 1

function rendercomments($args,$usersholder = NULL ){
    $args = $args + 1;
    // missing
    return true;
}

changeargs($args);
$userholder = 2
</code></pre>

<p>Can we do something like that? 
Someway to make $args append to $usersholder without returning it? </p>
