Passing optional number of arguments into another function
<p>Say I have a function called <code>addUp</code> which takes any number of decimal arguments and returns the result of them all added together.</p>

<p>If I have the following function:</p>

<pre><code>function myTest(){
    $args = func_get_args();
    return addUp($args);
}
</code></pre>

<p>If I call <code>myTest(1,2,3)</code> obviously this will not work as I'm only passing one argument to <code>addUp</code> and that is an array.</p>

<p>Is there a way to pass all the arguments passed into <code>myTest</code> on into the <code>addUp</code> function (without editing the <code>addUp</code> function)?</p>
