Transfer File us NuSOAP - php

Question

I am having a problem transferring files using NuSOAP. I understand that you can read a file and transfer it as a string, but it's not working. Here is an example:
Client:
require('libraries/nusoap/nusoap.php');
$url = "http://www.example.com";
$client = new nusoap_client($url);
args = array('file_name' => 'myfile.zip');
$return = $client->call('getFile', array($args));
if(empty($return){
echo "WHY IN THE WORLD IS THIS EMPTY!!!!!";
}
Server:
require('libraries/nusoap/nusoap.php');
$server = new nusoap_server;
$server->configureWSDL('server', 'urn:server');
$server->wsdl->schemaTargetNamespace = 'urn:server';
$server->register('getFile',
array('value' => 'xsd:string'),
array('return' => 'xsd:string'),
'urn:server',
'urn:server#getFile');
function getFile($value){
$returnData= "";
$filePath=$value['file_path'];
$mode="r";
if (floatval(phpversion()) >= 4.3) {
$returnData= file_get_contents($filePath);
} else {
if (!file_exists($filePath)){
return -3;
}
$handler = fopen($filePath, $mode);
if (!$handler){
return -2;
}
$returnData= "";
while(!feof($handler)){
$returnData.= fread($handler, filesize($filePath));
}//end while
fclose($handler);
}//end else
return $returnData;
}
Here is the really strange part. If I return the file name or file size or something like that, it will work. It will just not return the file itself. Help please.

In the server side getFile function you should return base64_encode($returnData);
