I tried and it works fine with PHP 5.4 and probably 5.6

but I think it stopped working with PHP 7.

This will be quite involved to try to get to work again, but we can see if that is a priority. For now, I think the best thing to do is to explain to clients that it will not work with PHP7 or higher.

FYI @samtuke

I will update the client, but I think we should check into this. Also It would be good to have the clients that are using the API.

I tried updating to a nusoap for PHP7, https://github.com/econea/nusoap

but that didn't work. It's likely that @xheni can find out how to fix this.

@michiel which version of nusoap do we use right now?

I think on the server, we use the latest. But it doesn't matter what's on the server. What we need is to fix the client to work with PHP7.

The client said that they may leave if we don't find a solution for this.

@xheni The client side library is quite simple. Do you think you can find the cause of the problem? If it is due to depreciated functions then simply enabling PHP error reporting should give a detailed explanation.

 @michiel I tried it with php5.6 and it's not working. On php7: The var_dump is giving me a string(1) "1" if it's true and string(0) " " if false, it returns null.
On php5.6 : it's bool(false) but it's returning null value .

Yes, I think it will only work on PHP5.4 or something.

When I run from cedar, it works fine

@michiel @xheni we will need an update for the client by tomorrow, this is pretty urgent to them

For now, you need to tell the client to use PHP5.4

I tested this under PHP 7 and PHP 5.6 and it misbehaves in both cases. This is my conclusion after some debugging:

NuSoap converts the SOAP datatypes in function decodeSimple to the PHP datatypes. NuSoap takes the response from the server for this and the current response is:

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:phpListHosted.isListSubscriberResponse xmlns:ns1="http://tempuri.org"><return xsi:type="xsd:bool"></return></ns1:phpListHosted.isListSubscriberResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>%

As you can see the datatype is set to xsd:bool but the decodeSimple function in the nuSoap library accepts only xsd:boolean. (the string after xsd: is passed to this function as $type)

function decodeSimple($value, $type, $typens) {
  // TODO: use the namespace!
  if ((!isset($type)) || $type == 'string' || $type == 'long' || $type == 'unsignedLong') {
     return (string) $value;
  }
  if ($type == 'int' || $type == 'integer' || $type == 'short' || $type == 'byte') {
     return (int) $value;
  }
  if ($type == 'float' || $type == 'double' || $type == 'decimal') {
     return (double) $value;
  }
  if ($type == 'boolean') {
     if (strtolower($value) == 'false' || strtolower($value) == 'f') {
        return false;
     }
     return (boolean) $value;
  }
  if ($type == 'base64' || $type == 'base64Binary') {
     $this->debug('Decode base64 value');
     return base64_decode($value);
  }


Also, the SOAP specs require boolean instead of bool (http://schemas.xmlsoap.org/soap/envelope/).
This is another example of another company using NuSoap server-side. By clicking on the API docs you can see that they use xsd:boolean: https://www.talend.com/TalendRegisterWS/registerws.php

This indicates to me that this is rather a server-side problem. To fix it I’d suggest one of the following approaches:

1. Add a new parsing behavior to the library but that would be a custom patch and then we would have to add the library to the repository as well.
2. Fix the issue server-side. I’d be happy to look it at but I don’t have access to the source code.

Let me know what would be your preferred option.
Thanks :)

can you test with PHP5.4? I would be surprised if it's server side, when the code works for existing systems.
The server runs php5.4

I can dig out the server side code, but we will have to be very careful changing that.

@xheni Excellent investigation work, thanks.

@michiel how about moving the Soap API code from Sourceforge to Github to make it easier to patch?

I also took a look at the details that client emailed and my guess was that they were not using the Soap client provided by phpList.
So I asked Suela to confirm that and turns out they are using https://paw.cloud to send the requests.

@samtuke Yes, definitely move the code from SF to Github. Where is it? I think the server code is on Gitlab though.

I think SF used to have the client code, but didn't you move that to Github already?

Closing since we found a workaround for the client.
