Hello,
I'm having a huge issue right now decoding a zip file from an attachment with a content-encoding of quoted-printable. I have tried a couple different methods (such as decoding the entire attachment or decoding it line by line), but none have produced a valid file when saved. What I don't understand is that I can download and open the file in Outlook fine, so there must be something wrong with the decoder. Here is a code snippet of my recent attempt:
elseif ($transferEncoding == 'quoted-printable'){
$fileError = true;
$attachmentParts = explode("\n", $currentPart->getContent());
$attachmentArray = array();
foreach ($attachmentParts as $line){
array_push($attachmentArray, quoted_printable_decode($line));
}
$attachment = implode("", $attachmentArray);
file_put_contents($unzipPath . '.zip', $attachment);
}
$unzipper = new Decompress(array(
'adapter' => 'Zip',
'options' => array(
'target' => $unzipPath,
)
));
$unzipper->filter($unzipPath . '.zip');
unlink($unzipPath . '.zip');
I'm using Zend Framework 2 methods for unzipping the file when it's done, but there is a CRC error because the file is getting corrupted during the decode.
This is how the file compares to the original (using Beyond Compare 3):
So it is finding the hex for CLRF and removing it from the file.
Any ideas on this would be greatly appreciated as I have been trying to solve this for about a month now.
Thanks,
