How can I start a for-loop with 01 instead of 1?
<p>How do I start a for-loop with <code>01</code> as opposed to <code>1</code>? I've tried the below, but it doesn't seem to work.</p>

<pre><code>for ($i = 01; $i &lt;= 12; $i++) {
    echo "&lt;option value='$i'";
    if ($i == $post_response[expiremm]) { 
        echo " selected='selected'"; 
    }
    $month_text = date("F", mktime(0, 0, 0, $i+1, 0, 0, 0));
    echo "&gt;$month_text&lt;/option&gt;"; 
} 
</code></pre>
