• BUGFIX: Publish Resources On Windows Without Admin Rights #3106

also the phpBinaryPathAndFilename always needs to be configured automatically.

By default (xampp) PHP_BINDIR will be C:\php which is totally wrong in my installation (should be some local directory inside xampp)

but PHP_BINARY contains the correct path, so im wondering if we should use it on windows instead, so one can at least compile flow via subprocess, and start the inbuilt server?

flow-development-collection/Neos.Flow/Configuration/Settings.Core.yaml

Lines 20 to 22 in aa38f57

	# Path and filename of the PHP binary
	# The constant PHP_BINDIR usually contains the path, but on Windows this doesn't work reliably
	phpBinaryPathAndFilename: '%PHP_BINDIR%/php'

edit: i think phpPathAndBinary should default to %PHP_BINARY% on windows in case %PHP_BINDIR%/php is invalid so that at least flow server run and flow configuration show works.

this can be realized when declaring flows environment variables. Wed need: FLOW_PHP_BINARY which can then be referenced in the configuration.
