ID: 55208 Updated by: f...@php.net Reported by: loco at andrews dot lv Summary: setting correct SCRIPT_NAME vs PHP_SELF is impossible in certain circumstances -Status: Open +Status: Feedback Type: Bug Package: FPM related Operating System: Gentoo Linux (2.6.39-gentoo-r3) PHP Version: 5.3.6 Assigned To: fat Block user comment: N Private report: N New Comment: SCRIPT_NAME is already defined in the fastcgi_params file. PHP_SELF doesn't have to be set in nginx as it's made in FPM. Can you try the following nginx configuration please ? location ~ ^.+\.php { include fastcgi_params; fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; vastcgi_param PHP_VALUE "include_path=$document_root:$document_root/include"; fastcgi_pass unix:/var/run/fastcgi/php-fpm.sock; try_files fastcgi_script_name =404; } it should be exactly the same as your configuration and it sould work. thx ++ jerome Previous Comments: ------------------------------------------------------------------------ [2011-07-17 08:02:25] loco at andrews dot lv Hi Jerome, I hope the information is now sufficient: ### nginx.conf: # http part with fastcgi configuration: http { fastcgi_pass_request_headers on; fastcgi_intercept_errors on; fastcgi_buffer_size 4k; fastcgi_buffers 1024 4k; index index.html; } # virtual host definition server { listen 80; server_name .mysite.com; access_log /var/log/nginx/mysite.access_log main; error_log /var/log/nginx/mysite.error_log warn; root /opt/www/mysite.com; location / { index index.php; } # if the request file name contains one of the below extensions, # serve it directly if ($request_filename ~* \.(css|js|ico|gif|png|bmp|jpe? g|tiff?)$) { break; } # otherwise, /index.php handles the request rewrite ^(.*)$ /index.php$1 last; location ~ ^(?<SCRIPT_FILENAME>.+\.php)(?<PATH_INFO>.*)$ { include fastcgi_params; fastcgi_param PATH_INFO $PATH_INFO; fastcgi_param PATH_TRANSLATED $document_root$PATH_INFO; fastcgi_param SCRIPT_FILENAME $document_root$SCRIPT_FILENAME; # Attention!

Thank you for your interest in PHP. Hi, I'm not able to reproduce the problem on my side. Can you please provide the following information: 1- nginx configuration (I need the doc_root and the fastcgi and location configuration): * server { * ... * root ...; * ... * location ~ \.php { * fastcgi_pass 127.0.0.1:9000; * fastcgi_split_path_info ^(.+\.php)(.*)$; * fastcgi_param PATH_INFO $fastcgi_path_info; * fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; * include fastcgi.conf; * } * } 2- PHP-FPM [pool] configuration 3- ini settings cgi.fix_pathinfo Thx ++ jerome ------------------------------------------------------------------------ [2011-07-14 15:55:40] loco at andrews dot lv Description: ------------ I am running nginx 1.0.4 with php-fpm and php 5.3.6. It seems that PHP_SELF has strong dependency on the setting of SCRIPT_NAME. When setting SCRIPT_NAME to something, $_SERVER['PHP_SELF'] will contain PHP_SELF environment value concatenated with environment value of SCRIPT_NAME. If SCRIPT_NAME is not set to anything, then $_SERVER['PHP_SELF'] contains what is passed to the environment, however, since SCRIPT_NAME is not set, PHP scripts that rely on SCRIPT_NAME will not work. Example #1: accessing URL: /index.php/some/url setting server variables: SCRIPT_NAME /some/url PHP_SELF /some/url result: print $_SERVER['SCRIPT_NAME']; // outputs: "/some/url" - OK print $_SERVER['PHP_SELF']; // outputs: "/some/url//some/url" - NOT OK! Example #2: SCRIPT_NAME (unset) PHP_SELF /some/url result: print $_SERVER['SCRIPT_NAME']; // outputs: "" print $_SERVER['PHP_SELF']; // outputs: "/some/url" Example #3: SCRIPT_NAME /some/url PHP_SELF (unset) result: print $_SERVER['SCRIPT_NAME']; // outputs: "/some/url" print $_SERVER['PHP_SELF']; // outputs: "" --- Bottom line: if configured as demonstrated in the first example, scripts that rely on SCRIPT_NAME will work properly, but scripts that require PHP_SELF won't work, as it contains the invalid URL; if configured as shown in the second example, scripts that rely on PHP_SELF work properly, but scripts that require SCRIPT_NAME, don't work at all; lastly, if configured as in the third example, scripts that use SCRIPT_NAME will work properly, but scripts that use PHP_SELF won't work, as PHP_SELF is empty. Any workaround for this issue? When using mod_php with apache, both SCRIPT_NAME and PHP_SELF can be set to the same value, and will be interpreted by PHP exactly like they are passed. However, in FCGI/PHP-FPM environment I cannot find a way to set them both to the same value! How is $_SERVER['PHP_SELF'] being constructed? Why should it rely on SCRIPT_NAME at all? How to set server environment correctly, so it is the same under FastCGI and under mod_php / apache 2.2? Andrejs Test script: --------------- <?php print '<pre>'; printf("SCRIPT_NAME: \"%s\"\n", $_SERVER['SCRIPT_NAME']); printf("PHP_SELF: \"%s\"\n", $_SERVER['PHP_SELF']); print '</pre>'; ?> Expected result: ---------------- I'd thought PHP_SELF should be possible to define explicitly through the server environment, without other variables affecting it's value. How come is it so that in the apache/mod_php mode both SCRIPT_NAME and PHP_SELF contain the same value? This does not seem to be possible in the FastCGI environment, at least when using php-fpm. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55208&edit=1
