SoapClient is enabled, but Class SOAPClient does not exist

[jangaehler]

I need PHPSoap in my Docker project and wanted to activate it now. The module is loading, phpinfo also shows it to me. But when I call var_dump(class_exists("SOAPClient")) I get a false. I tried all attempts from thread #315 , but nothing worked.
Some people say you have to install php-soap, which I can't do because php-soap has no installation candidate, others say it's not necessary.

Any ideas?

PHPInfo:

Soap Client	enabled
Soap Server	enabled
Directive	Local Value	Master Value
soap.wsdl_cache	1	1
soap.wsdl_cache_dir	/tmp	/tmp
soap.wsdl_cache_enabled	1	1
soap.wsdl_cache_limit	5	5
soap.wsdl_cache_ttl	86400	86400

My Dockerfile:

As noted in #315 (comment) and #75 (comment), soap requires libxml2-dev, I see you have installed that so the issue I would imagine is with some other environmental effect of yours

$ docker build -t php:test - << EOF
> FROM php
> 
> RUN apt-get update && apt-get install -y libxml2-dev --no-install-recommends
>

Thanks, it was a Layer 8 Error. I've copied var_dump(class_exists("SOAPClient")) from the interwebs and the quotation marks were the wrong ones.
