Sending Zip file via SOAP in PHP

Question

I have to send a file to a WSDL, the element is described in the WSDL as:

<s:element minOccurs="0" maxOccurs="1" name="theZipFile" type="s:base64Binary" />

How can I send the Zip file using SOAP Client? I have tried the following:

$client = new SoapClient($url);
$params = array("theZipFile" => "file.zip");
$response = $client->theFunction($params);

But I don't get the expected response. I have tried using .Net and C# with the following code:

string filename = "file.zip";
FileInfo fi = new FileInfo(filename);
long numBytes = fi.Length;
FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[] data = br.ReadBytes((int)numBytes);
br.Close();
fs.Close();

XElement response = client.theFunction(data);

And it works without any problem.

Thanks!

Where are you converting the byte stream to base 64 and did you verify that the zip file sent in the working code was still able to be opened? I think the .NET is automatically converting to base64 in contrast to PHP where you would have to do that manually. — Sean Anderson, Feb 28 '15 at 15:42

SoapClient wasn't sending the correct XML for some strange reason apparently was a problem with the definition.

Changed to use CURL.

function SOAPRawRequest($url, $postString, &$error) {
  $soap_do = curl_init(); 
  curl_setopt($soap_do, CURLOPT_URL,            $url );   
  curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10); 
  curl_setopt($soap_do, CURLOPT_TIMEOUT,        10); 
  curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);  
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false); 
  curl_setopt($soap_do, CURLOPT_POST,           true ); 
  curl_setopt($soap_do, CURLOPT_POSTFIELDS,    $postString); 
  curl_setopt($soap_do, CURLOPT_HTTPHEADER,     
    array('Content-Type: text/xml; charset=utf-8', 
      "Accept: text/xml",
      "Cache-Control: no-cache",
      "Pragma: no-cache",
      "SOAPAction: \"http://tempuri.org/theFunction\"",
      'Content-Length: '.strlen($postString)
    ));

  $result = curl_exec($soap_do);
  $error = curl_error($soap_do);

  return $result;
}

Also changed $params = array("theZipFile" => "file.zip"); to:

$content = file_get_contents("file.zip");
$content64 = base64_encode($content);

So was it the change to CURL or the actual encoding of the bytes to base64? Seems as though the original code would have sent raw binary which would have destroyed/invalidated your XML. — Sean Anderson, Feb 28 '15 at 20:08

You are passing a file name instead of file content to the soap call. Use

$params = array("theZipFile" => base64_encode(file_get_contents('path/to/a/file.zip')));
