I have tested using your exact description and get the result, you can
be fairly certain this is not something specific to your server/machine.
I would tend to agree with your premise - but the php devs may have
decided against this behaviour on purpose.
although I must also say it's a rather convoluted setup, then again you may
have a very good/neat reason for wanting to setup a directory akin to
your example.
because I was curious I tried the following, namely creating a subdir 'd'
in each of dirs 'a' and 'b' and creating the index.php in 'a/d/' a then symlinking
'a/d/index.php' to 'b/d/index.php' and then running the same tests using the 'd'
subdirs .... and guess what the correct [according to your expectation/opinion]
'ssi/a/inc' file was included
I would suggest maybe asking the internals@xxxxxxxxxxxx mailing list
as to whether they consider this a bug - and then file a bug report
if asked.
I might suggest also adding the following 2 lines to your test
index.php - which might provide a little more insight:
echo "the current working directory is ",getcwd(),"\n";
echo "I am the index file, my name is ",__FILE__,"\n";
additionally I changed the contents of your 'a.inc' files to the following:
<?php echo "I'm an included file, my name is ",__FILE__,"\n";
---------------
my conclusion:
no real answers, one possible way to workaround the problem,
possibly requires a little php-dev input.
