<p>The output of <code>print_r($node)</code> is the following.</p>

<pre><code>[field_pimage] =&gt; Array
        (
            [und] =&gt; Array
                (
                    [0] =&gt; Array
                        (
                            [fid] =&gt; 4
                            [alt] =&gt; 
                            [title] =&gt; 
                            [width] =&gt; 1440
                            [height] =&gt; 900
                            [uid] =&gt; 1
                            [filename] =&gt; 200801232112524201.jpg
                            [uri] =&gt; public://200801232112524201.jpg
                            [filemime] =&gt; image/jpeg
                            [filesize] =&gt; 122349
                            [status] =&gt; 1
                            [timestamp] =&gt; 1351403970
</code></pre>

<p>I want to output the <code>[uri]</code>'s value, how should I do it?</p>

<pre><code> $node-&gt;field_pimage-&gt;und-&gt;0-&gt;['uri'];  //but it doesn't work?
</code></pre>
