I have problems with relative paths and 4.3.0. Include() do not seem to work the same way in 4.3.0 and 4.2.1.This is mostly due to a characteristic of Solaris and a minor change in the way PHP handles includes (I guess):
1) Before parsing a script, PHP sets the directory of this script as the working dir. In pathnames and include_paths, '.' represents this directory, and '..' its parent, but PHP needs to getcwd in order to use them.
On Solaris, getcwd() needs "r" access to _all_ directories of the path, otherwise you get (from man getcwd):
EACCES A parent directory cannot be read to get its name.
It's not a bug, but a feature (seems strange to me).
2) If PHP can't find an included file in any directory of "include_path", it tries the directory of the main script in 4.2.1, and that of the including file in 4.3.0 (I guess that from my tests).
On my server, a directory of the script path was not readable by the user the server runs under. I fixed it, and now PHP is able to include the requested file by way of '..' in include_path.
