Nick was right, in most languages Geany(or better tagmanager) won't add
local variables to the symbol list. PHP is just one of the
exceptions ;-).

IMO not.

Yes but it is at all not a really a Geany bug but a bug in the PHP
parser of tagmanager/CTags (see tagmanager/php.c).
There are two possiblities:
- add the desired feature to the current parser(tagmanager/php.c),
should not be that difficult
- check whether the current CTags PHP parser supports the feature and
if so, backport it to tagmanager(it doesn't work without some more
work because there is something broken in regex.c, IIRC) and if not,
open a feature request to CTags tracker and request it and when it got
implemented get it working in Geany (see above ;-))

Enrico
