Include .php file in block body

i have had no problem with including any file from any directory as long as i specify the path.

what works for me is (this is not a real directory on my system):

include "sites/all/themes/mytheme/tab.php";

i can't imagine why nobody has responded to you before this, but i've had the same experience many times. i'm sure you've worked around it or figured it out yourself.

your include works when you put the file in your include directory. that's the norm. i'm not certain if it's a better way or a good way, but you can also do it two other ways:

1) relative path - first directory in path is the first directory under your "home" directory for your site in which your file is located. i put several include files in my site's (on a server-hence the normal slashes) "files" directory. drupal says 'sites/all/files' is that directory. therefore, if you put your include file there, you can include it by the relative-path method of include 'sites/all/files/tab.php'; i have a modification to the bluemarine theme/template, so, if i wanted it there and i wanted to include it somewhere, my relative-path include statement would be

include 'sites/all/themes/bluemarine/tlp_bluemarine/tab.php';

2) absolute path - specify the entire path to the file. using the same example as for 1) above:

include 'http://www.mysite.com/sites/all/themes/bluemarine/tlp_bluemarine/tab.php';

the absolute path will have to be changed everywhere I use it if I move my site out of the normal "www.mysite.com" url. the relative path will have to be changed everywhere i use it if I change my directory structure somewhere between "sites" and "tlp_bluemarine" or rename any of them.
