getting content of variables
<p>I am trying to learn PHP and stumbled across this problem of having bad keys in my array 
i have this function</p>

<pre><code>public function pdf_read_root()
{   
    $this-&gt;root = $this-&gt;pdf_resolve_object( $this-&gt;c, $this-&gt;pdf_find_root());

}
</code></pre>

<p>but <code>$this-&gt;root</code> is returning the wrong values, how do i get the individual contents, <code>$this-&gt;c &amp; $this-&gt;pdf_find_root</code> to see what is being used in <code>pdf_resolve_object</code></p>
