#21261 [Com]: $_SERVER['PHP_SELF'] gives wrong info

ID: 21261 Comment by: tapken@engter.de Reported By: undream@yifan.net Status: Open Bug Type: Scripting Engine problem Operating System: linux 2.4.18 - slack 8.1 PHP Version: 4.3.0 Assigned To: shane New Comment: Sorry, my PHP-Based Workaround seems to be buggy in some cases, too... Here is a quick & dirty bugfix for the quick & dirty workaround :-) Btw, it would be nice if the bug is fixed in PHP 4.3.1... -snip---------------------------------------- // Small Workaround for a bug in PHP 4.3.0/cgi // See http://bugs.php.net/bug.php?id=21261 for details $_SERVER['SCRIPT_NAME'] = substr($_SERVER['PATH_TRANSLATED'], strlen($_SERVER['DOCUMENT_ROOT'])); if (substr($_SERVER['SCRIPT_NAME'], 0, 2) == '//') { $_SERVER['SCRIPT_NAME'] = substr($_SERVER['SCRIPT_NAME'], 1); } $PHP_SELF = $SCRIPT_NAME = $_SERVER['PHP_SELF'] = $_SERVER['SCRIPT_NAME']; -snip------------------------------------ Previous Comments: ------------------------------------------------------------------------ [2003-01-13 11:41:12] daniel.gorski@develnet.org That (or similar) urgent problem occurs here too. PHP versions before mid december were not affected IMO. At first today I've checked out the "php4" and "php5" modules from CVS, configured, and build them. After installation of the CGI binaries I detected a problem with $_SERVER['PHP_SELF']: a) the PHP4 version shows "no value" b) the PHP5 version shows illegal characters, cut off strings with low ASCII values etc. Depending on the namebased vhost name the value of PHP_SELF looks like "ind##" instead of "index.php" ("#" should represent low ASCII chars, which are shown as boxes here) of just "5" which is definitely the last char of "index.php5". Short: looks like a pointer on a string array is bent somewhere. The problem insist with and without '--enable-force-cgi-redirect' in both versions. As an example you may want to take a look at http://daniel-gorski.de/index.php4 (PHP4 CGI) http://daniel-gorski.de/index.php5 (PHP5 CGI) and compare the values of $_SERVER['PHP_SELF']. Additionally the PHP5 version has a strange "Zend Extension" date: 90021012. OTOH this value seems to be correct in the PHP4 version. The operating system is Linux (RedHat 6.2). I would appreciate to see this bug solved as soon as possible, because this is a dramatic show stopper for a few ZE2 applications I am developing & running. What required information can I provide to help to solve this problem? regards dtg ------------------------------------------------------------------------ [2003-01-09 14:57:05] tapken@engter.de Quick & Dirty PHP-Based workaround: Put this code in a file and add it to auto_prepend_file-directive in php.ini: -snip---------------------------------------- // Small Workaround for a bug in PHP 4.3.0/cgi // See http://bugs.php.net/bug.php?id=21261 for details $_SERVER['SCRIPT_NAME'] = substr($_SERVER['PATH_TRANSLATED'], strlen($_SERVER['DOCUMENT_ROOT'])); $PHP_SELF = $SCRIPT_NAME = $_SERVER['PHP_SELF'] = $_SERVER['SCRIPT_NAME']; -snip------------------------------------ Works fine for me... If PHP is used as CLI it may be neccessary to check current mode before running this code. ------------------------------------------------------------------------ [2003-01-07 13:30:23] tapken@engter.de There is no space in SCRIPT_NAME on my localhost, this was an copy&paste-error. But the "I" at the end exists. ------------------------------------------------------------------------ [2003-01-07 13:27:55] tapken@engter.de Same for me, your patch seems to have no affect. I checked the debugging output from cgiwrap which says: [...] Fixing Environment Variables. Environment Variables: QUERY_STRING: '' SCRIPT_NAME: '/phpinfo.php' SCRIPT_FILENAME: '<DOCUMENT_ROOT>/phpinfo.php' REDIRECT_URL: '<NULL>' PATH_INFO: '/phpinfo.php' PATH_TRANSLATED: '<DOCUMENT_ROOT>/phpinfo.php' REMOTE_USER: '<NULL>' REMOTE_HOST: '<NULL>' REMOTE_ADDR: '217.4.137.70' [...] Seems to be ok?! But PHP_SELF has no value. On my localhost PHP 4.3/CGI works with cgiwrap. The same paragraph with this machine: [...] Fixing Environment Variables. Environment Variables: QUERY_STRING: '' SCRIPT_NAME: '/php/ phpinfo.phpI' SCRIPT_FILENAME: '<DOCUMENT_ROOT>/php/phpinfo.php' REDIRECT_URL: '' PATH_INFO: '/php/phpinfo.php' PATH_TRANSLATED: '<DOCUMENT_ROOT>/php/phpinfo.php' REMOTE_USER: '' REMOTE_HOST: '' REMOTE_ADDR: '192.168.23.2' [...] In this case, script_name is broken for some reason (don't ask me why, i didn't find out). But PHP_SELF has the correct value! On both server SCRIPT_NAME isn't listed in the phpinfo()-Output. Hope this will help. ------------------------------------------------------------------------ [2003-01-07 00:42:23] shane@php.net undream@yifan.net: email me your httpd.conf, php.ini and the test script you use. You can remove anything from the files that are private. Also, as per spec PATH_TRANSLATED will be empty unless you have PATH_INFO, which is path data *after* the script in a url: http://host/script.php/path/info?query-string The only thing I'm concerned about is the garbled PHP_SELF. PHP_SELF is the same as SCRIPT_NAME, is SCRIPT_NAME also garbled? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
