With PHP, GET parameters may be specified as command-line arguments, which is a [valid form of input](https://codegolf.meta.stackexchange.com/a/2449/45941) by our rules. However, they *must* be passed in the form `argname=value` on the command line, because [`register_globals`](http://php.net/manual/en/ini.core.php#ini.register-globals) is off by default, and we assume a default configuration. After an [exchange](https://codegolf.stackexchange.com/a/64829/45941) in the comments of an answer, I'd like to get clarification/consensus on how to score this.

Note that this does not concern the use of `$argv` parameters.
