I think this is a bug in Xdebug. It is because Xdebug scans the function
for variables names to show them in the list to the IDE. However, when
the function is defined/declared, Xdebug doesn't know that extract is
going to create new variables. Obviously, it should be able to figure
this out, so this is a bug. Would you mind filing a bug report at
http://bugs.xdebug.org so that I don't forget?

cheers,
