Dissapearing PHP Variables
<p>I am creating a 3D Secure PHP Project. I am having a rather bizzare issue in that the "MD" code is going missing when re-submitting the Array of data</p>

<p>My code is as follows :</p>

<pre><code>$paRes = $_REQUEST['PaRes'];
$md = $_REQUEST['MD'];

require "payment_method_3d.php";


x_load('cart','crypt','order','payment','tests');

/*
* For Debugging Purposes
* Only.

echo "The Value Of PaRes is : ";
echo $paRes;
*/

$soapClient = new SoapClient("https://www.secpay.com/java-bin/services/SECCardService?wsdl");

$params = array (
    'mid'           =&gt; '',
    'vpn_pswd'      =&gt; '',
    'trans_id'      =&gt; 'TRAN0095', // Transaction ID MUST match what was sent in payment_cc_new file
    'md'            =&gt; $md,
    'paRes'         =&gt; $paRes,
    'options'       =&gt; ''
);
</code></pre>

<p>It seems that the $_REQUEST['MD'] string seems to go missing AFTER the soap call. Although I am having difficulty print this out to the screen. The strange thing is the $paRes variable works without issue.</p>

<p>Any ideas why this would be the case?</p>
