#31892 [Com]: PHP_SELF incorrect without cgi.fix_pathinfo, but turning on screws up PATH_INFO

ID: 31892 Comment by: php-bugs at dave dot staff dot spoonguard dot org Reported By: ceefour at gauldong dot net Status: Verified Bug Type: CGI related Operating System: * PHP Version: 5CVS, 4CVS (2005-02-11) New Comment: The following patch causes $_SERVER['PHP_SELF'] to include the PATH_INFO component when running under CGI: http://spoonguard.org/dave/classes/cs345/bugfix/php-5.1.2-31892.diff Previously, PHP_SELF was being set to SCRIPT_NAME when cgi.fix_pathinfo was set. This changes the behavior, by setting PHP_SELF to SCRIPT_NAME + PATH_INFO. Is this similar to what you're looking for? Thanks, - Dave Previous Comments: ------------------------------------------------------------------------ [2005-02-13 23:19:43] ceefour at gauldong dot net I have verified this problem with PHP 5.0.3 on Linux 2.4 and it also exists in PHP 5.0.3. I'm using PHP 5.0.3 as CGI under Apache 1.3.33. Check out this link: http://php5.gauldong.net/phpinfo.php/test/me?query=string It gives out the following results: _SERVER["PATH_INFO"] /test/me _SERVER["PATH_TRANSLATED"] /home/u1294/domain/php5.gauldong.net/web/test/me _SERVER["ORIG_PATH_TRANSLATED"] /home/u1294/domain/php5.gauldong.net/web/phpinfo.php/test/me _SERVER["ORIG_PATH_INFO"] /phpinfo.php/test/me _SERVER["ORIG_SCRIPT_NAME"] /cgi-bin/php _SERVER["ORIG_SCRIPT_FILENAME"] /home/u1294/domain/php5.gauldong.net/web/cgi-bin/php _SERVER["PHP_SELF"] /phpinfo.php ----- Note that it's using a default php.ini for PHP 5 meaning cgi.fix_pathinfo is turned ON. In the above results PHP_SELF is incorrect. It should be /phpinfo.php/test/me (it's missing the pathinfo part). Other variables are correct I suppose. I hope this is fixed soon. And also in PHP 4. The fact that this bug exists in the latest versions of both PHP 4 and PHP 5 is truly beyond me. :-( ------------------------------------------------------------------------ [2005-02-09 09:34:50] ceefour at gauldong dot net Description: ------------ Following up bug #31843, I tried to set cgi.fix_pathinfo On, which is "weird" considering that this option says ANYthing about PHP_SELF. But a good friend of mine pointed out it works on fixing PHP_SELF, so I did, and to my surprise, it works! So, my problem was solved, PHP_SELF was returning the correct value... though not in a very elegant way, in my opinion, since who has access to some hosting server's php.ini? Everyone but the most elite premium services, I guess. Nonetheless it worked, so I enjoyed cherish, fortune, and glory... for several seconds. It turned that turning on cgi.fix_pathinfo actually screws up PATH_INFO, at least in my configuration, which is VERY strange considering the name of the option (shouldn't it be cgi.fix_phpself_and_screw_up_pathinfo???) ;-) Let me apologize for a bit of sinism but really it was just for making fun out of it. So, phpinfo() says PATH_INFO and PATH_TRANSLATED is now "no value". Something's good though, ORIG_PATH_* returns the correct value (weird). It's possible to use ORIG_PATH_* but I guess I should stick to the standards. Since that server was in heavy use, I quickly realized that by just turning that option on, I could have caused many pages to fail (since they rely on PATH_INFO) so I quickly turn this option off again (I already had a workaround for PHP_SELF bug, it's not a problem anymore but I'm still seeking for an elegant resolution on this, in the part of PHP developers not in my part). Reproduce code: --------------- phpinfo() Expected result: ---------------- PHP_SELF: phpinfo.php/test/me PATH_INFO: /test/me Actual result: -------------- cgi.fix_path_info=Off: PHP_SELF: /test/me PATH_INFO: /test/me cgi.fix_path_info=On: PHP_SELF: phpinfo.php/test/me PATH_INFO: (no value) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31892&edit=1
