Changing include path using php script

Question

I'm looking to include other folders in my include path for PHP. I've seen this question:

Setting PHP Include Path on a per site basis?

BUT I don't want to replicate the system path (I suppose I could but then it won't update if the system path is updated). What I would rather is to simply have a line which looked like:

ini_set('include_path', ini_get('include_path').$otherpaths);

Will this work, and is there some fundamental readon this is bad?

Answer 1

I think you are looking for this: set_include_path

With it, you can do:

set_include_path(get_include_path() . PATH_SEPARATOR . $otherpath);
