The issue is most likely due to the extension(php_rdkafka.dll) that you are trying to install, if your php version is thread safe(ts) then ensure that you have downloaded and installed an extension which is thread safe otherwise use a non-thread safe(nts) extension. In addition to that also ensure that both the extension and php are of the same architecture i.e x86 or x64.

Use php_rdkafka.dll for php version 7.1.

You can verify thread safe status and architecture of the installed php in phpinfo page(see below);
