ID: 6795 Updated by: sniper Reported By: drew@elysium.ltd.uk Old-Status: Closed Status: Open Bug Type: Apache related Assigned To: Comments: Reopened per user request. Problem still exists with php4.0.4pl1 --Jani Previous Comments: --------------------------------------------------------------------------- [2000-12-30 14:05:49] sniper@php.net No feedback, considered fixed. --Jani --------------------------------------------------------------------------- [2000-12-04 09:01:27] sniper@php.net Could you please check if this problem exists when using the PHP 4.0.4RC3: http://www.php.net/distributions/php-4.0.4RC3.tar.gz --Jani --------------------------------------------------------------------------- [2000-09-17 19:49:16] drew@elysium.ltd.uk There seems to be a problem with the values of $PATH_TRANSLATED under different circumstances :- In your Apache document_root create the following files :- .htaccess AddHandler testhandler .test Action testhandler handler.phtml handler.phtml <? print "PATH_TRANSLATED = $PATH_TRANSLATED"; ?> index.test Content not used You will need AllowOverride All (or similar) in the Directory spec for your Apache document root (to all adding handlers). Here is a list of requests and responses http://localhost/index.test - PATH_TRANSLATED = /home/httpd/html/handler.phtml (Incorrect) http://localhost/handler.phtml - PATH_TRANSLATED = /home/httpd/html/handler.phtml (Correct) http://localhost/index.test/path_info - PATH_TRANSLATED = /home/httpd/html/handler.phtml (Incorrect) http://localhost/handler.phtml/path_info - PATH_TRANSLATED = /home/httpd/html/handler.phtml (Incorrect) The reason I have put incorrect for 3 of the tests is that the value differs from the value of PATH_TRANSLATED that Apache provides. PHP just copies the value of SCRIPT_FILENAME over the top of PATH_TRANSLATED. Please find attached a patch to make to responses the same as Apache's version of PATH_TRANSLATED. http://localhost/index.test - PATH_TRANSLATED = /home/httpd/html/index.test (Correct) http://localhost/handler.phtml - PATH_TRANSLATED = /home/httpd/html/handler.phtml (Correct) http://localhost/index.test/path_info - PATH_TRANSLATED = /home/httpd/html/index.test/path_info (Correct) http://localhost/handler.phtml/path_info - PATH_TRANSLATED = /home/httpd/html/path_info (Incorrect) Not really sure whats going on with the last test - bug in Apache. There is also a pretty big bug in Apache when doing these type of tests from a public_html (~user) type of directory.
