I strongly suspect that this regexp is applied to a stream of *bytes*,
whereas in phps-mode you're dealing with a stream of *characters*.

IOW for the re2c code, `λ` is the two byte sequence of \xCE and \xBB
(assuming the file is using utf-8) whereas in phps-mode it's just `λ` or
\u03BB.

So the regexp above actually matches all the non-ascii Unicode chars,
assuming the file uses utf-8.

In that case, maybe

    [[:alpha:]_][[:alnum:]_]*

is the saner choice.
