What you say is correct. This is an Apache HTTP Server mailing list. You said, in apache, I cannot find any code which assign this var. and I showed you where in Apache HTTP Server the DOCUMENT_ROOT environment variable is set when running CGIs. What you are now asking should be sent to the PHP users mailing list, since it is a question about PHP. But, see the function init_request_info() in the PHP source code, in the file sapi/cgi/cgi_main.c (lines 1123-1137) http://svn.php.net/viewvc/php/php-src/branches/PHP_5_3_8/sapi/cgi/cgi_main.c?revision=315335view=markup How PHP determines the value of $_SERVER[DOCUMENT_ROOT] depends on all of the following: - The value for the PHP directive cgi.fix_pathinfo - The value for the PHP directive doc_root - The value of the environment variable DOCUMENT_ROOT (set by Apache HTTP Server) -- Mark Montague m...@catseye.org
questions about document_root
Hi, I want to modify apache core to implement a function which can achieve following expectations: when I request 1000.xxx.com/test.php ( curl 1000.xxx.com/test.php), originally apache will get absolute address as $document_root/test.php, but I want apache to get $document_root/1000/test.php. Namely, apache will parse 1000 from the request URI to form absolute address. Then php-cgi can get this php script to execute. Previously, I just modified PHP zend to achieve this function. But considering that other language support would be added to the system such as Python, therefore, modifying Web Server (apache) is a more convenient way. But I'm worried that this modification will result in some unexpected errors in some modules, and I don't know what's the best place I should modify. Should I modify the $document_root or $request_uri ? Really appreciate your help. -- Best regards, Rui Hu State Key Laboratory of Networking Switching Technology Beijing University of Posts and Telecommunications(BUPT) MSN: tchrb...@gmail.com -

Re: questions about document_root
Thanks for you advice. I just started to learn Apache PHP. I looked up the code of PHP and apache2, and found that PHP gets docroot from environment var $DOCUMENT_ROOT. However in apache, I cannot find any code which assign this var. 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! 2011/12/7 Nick Kew n...@webthing.com On 7 Dec 2011, at 10:54, Rui Hu wrote: Hi, I want to modify apache core to implement a function which can achieve following expectations: That's a simple task for a simple module.

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, https://svn.apache.org/viewvc/httpd/httpd/branches/2.2.x/server/util_script.c?revision=1100216view=markup -- Mark Montague m...@catseye.org

In above code, rc-t is a variables of httpTtrans. 2011/12/8 Mark Montague m...@catseye.org On December 7, 2011 23:23 , Rui Hu tchrb...@gmail.com wrote: I looked up the code of PHP and apache2, and found that PHP gets docroot from environment var $DOCUMENT_ROOT.
