Hi all
I'm reviewing a few things before starting a new project. I often need to
include() a file relative to the current script which itself is included.
__FILE__ is useful to know the current script's path but it seems to be
totally undocumented at php.net except for a few indirect references and
user comments. Is it still current? I don't want to use something that might
disappear soon but I haven't found any of the newer variables that do the
same thing.
Unfortunately __FILE__ is difficult to search for on php.net because you end
up seeing the result simply for 'file' which is not very helpful.
Perhaps my real question should be:
What is the cleanest and self-contained way to do a relative include from an
included file which might not be in the same directory as its parent? A
change in PHP 4.1 almost solved this but not quite. If it doesn't find the
file in the include_path then it looks in the same directory as the current
script. IMHO, its doing it in the wrong order. It would make more sense to
check the currect directory first before trying the include_path. Putting a
dot as the first element of the include_path doesn't fix it because the dot
means the current directory of the top parent.
Cheers
Ross
