Actually I'm using php-mode within html-mode, plus mmm-mode.
Now the identation of PHP code is poor in this condition. After
reading some code doing the identing job I found it is possible
to solve this by set such a "goal column," since most of them
count the column from column 0 by go to there with 'beginning-
of-line'. If we could set this column, a few modifications to mmm-
mode will make it handle identation better.

Another method is to modify the identing code to use another
function to go to the "beginning" of a line instead of 'beginning-
of-line', but this could be more difficult.

I'll take a look at the field property now. But 'avoid-columns-1-7'
is not proper due to my confusing description.
