#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 New Comment: I have a similar problem. It is discribed in http://bugs.php.net/bug.php?id=21301 The result of set cat be viewed on http://www.engter.de/shenv.php Previous Comments: ------------------------------------------------------------------------ [2002-12-30 10:59:11] undream@yifan.net 'set' alone does not give PATH_INFO but I explicitly called a few vars. Note that I had to run it from the cgi-bin dir, but they were the same for php 4.3.0 and 4.2.3: -----CGI/1.0 test script with cgi php 4.3.0 OR 4.2.3----- SERVER_SOFTWARE = Apache/1.3.27 (Unix) SERVER_NAME = localhost.localdomain GATEWAY_INTERFACE = CGI/1.1 SERVER_PROTOCOL = HTTP/1.1 SERVER_PORT = 80 REQUEST_METHOD = GET HTTP_ACCEPT = text/*, image/jpeg, image/png, image/*, */* PATH_INFO = PATH_TRANSLATED = SCRIPT_NAME = /cgi-bin/test-cgi QUERY_STRING = REMOTE_HOST = REMOTE_ADDR = 127.0.0.1 REMOTE_USER = AUTH_TYPE = CONTENT_TYPE = CONTENT_LENGTH = I also posted the phpinfo() fron php cgi 4.2.3 at http://www.undream.com/php/env-4.2.3.html. The php_self is correct there. Nothing else has changed. I also played around with calling php_info() from various directories. Sometimes pieces of the php_self path are hopped, sometimes it is not even set. It is very consistent. I did not notice any pattern (i.e chopping off the first x letters everytime) ------------------------------------------------------------------------ [2002-12-29 19:51:28] pollita@php.net I have a theory, but I need you to run one more test: 1) Create a CGI shell script "/var/www/htdocs/shenv.sh" with the following content: #!/bin/sh set 2) Be sure to chmod it so that it can be executed by the webserver then browse to it (i.e.: http://localhost/shenv.php ) Post the results here. My theory is that Apache is not setting the CGI environment variables "SCRIPT_NAME" or "PATH_INFO" correctly. But I can at least tell you one thing for sure... The "ocs" in "ocs/env.php" is comming from the last three characters in the file's true path "/var/www/htdocs/env.php" ------------------------------------------------------------------------ [2002-12-29 14:05:27] undream@yifan.net A strace dump for the following page content: <?php echo $_SERVER['PHP_SELF']; ?> called from url: http://localhost/test.php can be found at: http://www.undream.com/php/bug-21261.log The PHP_SELF result for that one was :PHP/4.3.0 I also have a phpinfo dump of my setup at: http://www.undream.com/php/env.html This last one was called using http://localhost/env.php url. As you can see, the PHP_SELF result is equally weird. ------------------------------------------------------------------------ [2002-12-28 22:51:32] pollita@php.net 1) What webserver are you running? (and what version?) 2) Since you are running as a CGI can you please do an strace on this page? Example (correct the file paths as necessary, you may need to install strace first): strace /usr/local/bin/php -f /var/www/env.php 2> /var/www/bug-21261.log Provide a URL to this strace so that the problem can be further diagnosed. ------------------------------------------------------------------------ [2002-12-28 22:05:09] undream@yifan.net A call to http://localhost/env.php with env.php containing a phpinfo() call returns this for $_SERVER['PHP_SELF'] = ocs/env.php I have no idea what 'ocs' is. This is run on a Konqueror 3.1 browser. PHP is ran as CGI. Previous php (4.2.3) compiled using the _exact_ same setup gives the correct info (localhost/env.php) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21261&edit=1
