Looking at the current websites here:
I wonder if the toolkit is still supported? Seems to me, that since 2010 no updates have been made. It's still on v20.0, however it seems to be possible to replace the wsdl and endpoint-url to use v31.0. I only tried a simple query, but at least got some promising results.
Is it still recommended to use it? Or is there something else to access Salesforce via php? Anyone got more experience with it? Is it reliable with wsdl > v20.0?
Is this toolkit the right choice for php-based heroku projects to interact with salesforce?
