PHP - Passing a variable to a function without passing variables asked before it?
<p>Is it possible to pass a variable to function without passing the variables that come before it in the function definition?</p>

<p>For example, if my function looks like this:</p>

<pre><code>function doThis( $v1, $v2, $v3 )
{
    echo $v1.$v2.$v3;
}
</code></pre>

<p>Can I then call the function with only some of those variables, like <code>doThis("v1",null,"v3")</code> or some other way?</p>
