Numbering with prefix of zero in PHP
<p>Is it possible in PHP to echo out a number with zeroes at the beginning?</p>

<p>For example</p>

<pre><code>&lt;?php

$i = 0001;
$i++;
echo $i;

?&gt;
</code></pre>

<p>And when it print out, I want it to be like.</p>

<pre><code>0002
</code></pre>

<p>Is it possible? Thanks :)</p>
