Printing a gif from a variable with php - php

Question

I am experimenting with the Endicia shipping label server. The sample code below allows me to get a USPS label from their test server. How would I display the image that is being returned. Right now the print_r function (if un-commented out) does print out the array contents of what appears to be an image.
<?php
$strGetLabelURL = "https://www.envmgr.com/LabelService/EwsLabelService.asmx/GetPostageLabelXML";
$request = '<LabelRequest ImageFormat="GIF" Test="YES">
<RequesterID>abcd</RequesterID>
<AccountID>123456</AccountID>
<PassPhrase>samplePassPhrase</PassPhrase>
<MailClass>FIRST</MailClass>
<DateAdvance>0</DateAdvance>
<WeightOz>1</WeightOz>
<Stealth>FALSE</Stealth>
<Services InsuredMail="OFF" SignatureConfirmation="OFF" />
<Value>0</Value>
<Description>Sample Label</Description>
<PartnerCustomerID>12345ABCD</PartnerCustomerID>
<PartnerTransactionID>6789EFGH</PartnerTransactionID>
<ToName>Ben Franklin</ToName>
<ToCompany>United States Postal Service</ToCompany>
<ToAddress1>12345 Main Street</ToAddress1>
<ToCity>Camas</ToCity>
<ToState>WA</ToState>
<ToPostalCode>98607</ToPostalCode>
<ToPhone>2025551212</ToPhone>
<FromName>Technical Support</FromName>
<FromCompany>DYMO Endicia</FromCompany>
<ReturnAddress1>385 Sherman Ave.</ReturnAddress1>
<FromCity>Palo Alto</FromCity>
<FromState>CA</FromState>
<FromPostalCode>94306</FromPostalCode>
<FromZIP4>1864</FromZIP4>
<FromPhone>8005763279</FromPhone>
</LabelRequest>';
$params = array('http' => array(
'method' => 'POST',
'content' => 'labelRequestXML='.$request,
'header' => 'Content-Type: application/x-www-form-urlencoded'));
$ctx = stream_context_create($params);
$fp = fopen($strGetLabelURL, 'rb', false, $ctx);
if (!$fp)
{
print "Problem with $strGetLabelURL";
}
$response = stream_get_contents($fp);
if ($response === false)
{
print "Problem reading data from $url, $php_errormsg";
}
print_r($response);
?>

Answer 1

You have to load the XML, extract the image data, then put it in an image:
$sxml = Simplexml_load_string( $response );
echo '<img src="data:image/gif;base64,' . $sxml->Base64LabelImage . '">';

Answer 2

I don't know about Endicia solution but I think it's quite similar to UPS.
From the XML you send one can see that you ask for the label in GIF format.
I suppose that in the response you have an element named <LabelImage> or something similar. You need to extract the value that is between the opening and the closing tag and use below to print it on your browser:
echo '<img src="data:image/gif;base64,' . $value . '" alt="" />';
