Php: 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 https://github.com/docker-library/php/issues/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:
```FROM php:7.1-apache

As noted in https://github.com/docker-library/php/issues/315#issuecomment-264645332 and https://github.com/docker-library/php/issues/75#issuecomment-131795436, 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

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.
