How can I display binary image data as an Image in PHRETS

Question

I am using http://otw.rets.interealty.com/Login.asmx/Login I am getting image as Binay Data. How can I display a binary data from RETS as an Image. Here is my code

$sysid = $data['sysid'];
$photos = $rets->GetObject("Property", "Photo", $sysid, "*", 1);
echo $photos[0]['Data'];

Answer 1

According to the PHRETS documentation for GetObject, the last argument in GetObject, $location, can either be a "0" or "1". "1" returns the image's URL string and "0" returns the binary image data.

#1 Encoding the image data and outputting to browser without saving to a file. From this SO question

$photos = $rets->GetObject("Property", "Photo", $sysid, "*", 0);
foreach ($photos as $photo) 
{

    if ($photo['Success'] == true) 
    {
        $contentType = $photo['Content-Type'];
        $base64 = base64_encode($photo['Data']); 
        echo "<img src='data:{$contentType};base64," . $base64 . "' />";
    }
    else 
    {
        echo "({$photo['Content-ID']}-{$photo['Object-ID']}): {$photo['ReplyCode']} = {$photo['ReplyText']}<br />";
    }

}

#2 Saving the image to a file and then displaying it. From PHRETS

$photos = $rets->GetObject("Property", "Photo", $sysid, "*", 0);
foreach ($photos as $photo) 
{

    if ($photo['Success'] == true) 
    {
        file_put_contents("image-{$listing}-{$number}.jpg", $photo['Data']);
        echo "<img src='image-{$listing}-{$number}.jpg' />";
    }
    else 
    {
        echo "({$photo['Content-ID']}-{$photo['Object-ID']}): {$photo['ReplyCode']} = {$photo['ReplyText']}<br />";
    }

}
