PHP External Task

GChester1 · February 20, 2021, 4:03am

I’m trying to figure out how to call a PHP script as an external task.

I see there is the PHP SDK, but it seems quite old.

I’ve also seen the example on Github but it uses the PCNTL Extensions which are Unix only and we are using Windows.

Does anyone have any suggestions?

Thanks in advance.
