Need help on set up sapnwrfc for WAMPSERVER (Apache 2.4.35, PHP 7.2.10) on windows server 2016

Hi there,

Our previous platform is Apache 2.2.8, PHP 5.2.5, I got the SAPRFC externsion through this place http://saprfc.sourceforge.net/. I figured out and made it work. Now we are upgrading the platform to "Apache 2.4.35, PHP 7.2.10", the old SAPRFC extension does not work now. I searched online, seems I need have the new sapnwrfc extension. But I have not found much helpful information for how to set up yet. there is one site https://gkralik.github.io/php7-sapnwrfc/installation.html, but seems building from source is kind complicated. Is there any already built extension available to match my environment?

And also now is it better to access the SAP through SAP web service?

Thanks for help.
