php5 include() problem

I've got a cgi file in my cgi-bin folder that I'm calling with include(). It worked with php4. My shared host just upgraded to my server to php5.2.0 and the function doesn't work. I can't tell if the problem is a php5 or server configuration [which may have changed during the upgrade] issue. If I call the file as a URL directly, it works. http://www.foo.org/cgi-bin/file.cgi?dir=/test&perms=0755 file.cgi chmods the designated directory's permissions. It's a cgi with a php shebang #!/usr/bin/php A simple file_exists() shows the file exists OK, TRUE. I've tried using both syntaxes. include("/home/foo/public_html/cgi-bin/file.cgi?dir=test&perms=0755"); include("www.foo.org/cgi-bin/file.cgi?dir=test&perms=0755"); Here is the error msg:

Warning: include(/home/foo/public_html/cgi-bin/file.cgi?dir=/test&perms=0755) [function.include]: failed to open stream: No such file or directory in /home/foo/public_html/EditPage/cgi_file_test.php on line 15

Bottom line: It appears include() is not working right, for whatever reason. Anyone have any ideas? Thanks, Al........
