I looked up the code of PHP and apache2, and found that PHP gets

I googled but got nothing. Can you please show me the detailed process
generating $DOCUMENT_ROOT in $_SERVER from apache to php. Thank you
very much!
If you invoke PHP as a CGI, then Apache HTTP Server sets DOCUMENT_ROOT
in the function ap_add_common_vars() which is in the file
server/util_script.c
See line 237,
