<div class="content wysiwyg-content">
If I have user input of 0812, I need the variable to be changed to 1208. &nbsp;So my quick attempt to do this is:<br />
<br />
$expiry_date=$_POST[abc]; //'1308' YYMM<br />
$backwardsExpiry = sprintf(&quot;%02d&quot;,substr($_PO<wbr />ST[abc],3,<wbr />2)).sprint<wbr />f(&quot;%02d&quot;,s<wbr />ubstr($_PO<wbr />ST[abc],0,<wbr />2));<br />
print(&quot;Expiry = &quot;&nbsp;. $expiry_date.&quot;&lt;br&gt;&quot;);<br />
print(&quot;Backwards = &quot;&nbsp;. $backwardsExpiry.&quot;&lt;br&gt;&quot;);<br />
<br />
The print out is <br />
0812<br />
0208<br />
<br />
How do I fill only if it comes back as 8 rather than 08?

If I have user input of 0812, I need the variable to be changed to 1208.  So my quick attempt to do this is:

$expiry_date=$_POST[abc]; //'1308' YYMM
$backwardsExpiry = sprintf("%02d",substr($_POST[abc],3,2)).sprintf("%02d",substr($_POST[abc],0,2));
print("Expiry = " . $expiry_date."<br>");
print("Backwards = " . $backwardsExpiry."<br>");

The print out is 
0812
0208

How do I fill only if it comes back as 8 rather than 08?
