No environment variables are available via PHP-fpm+nginx

Question

I tried to modify php.ini in the following way:

variables_order = "GPCSE"
register_globals = On

But the required PATH variable is neither in $_ENV nor accessible via getenv('PATH').
I'm running Nginx + PHP-FPM on Ubuntu 10.04.

Note: executing the following command in console gives a correct result:

php -r "echo getenv('PATH');"

I guess that PATH is environment variable of bash, but as long as php-fpm not starting via bash it doesn't have required variables. Any way to include them?

Thanks.

Update#1: As temporary solution I found out that PATH variable stored in '/etc/environment' file. So I just going to read it from there. If someone needs a code:

preg_match('/^(PATH)="?([^"]+)"?$/i', file_get_contents('/etc/environment'), $match);
putenv($match[1]."=".$match[2]);

Solution 1

I came across this problem when upgrading my OwnCloud installation to version 8.1.

They describe a fix in their documentation

Summary is: Locate your www.conf file in your php5-fpm config folder (for Ubuntu this is /etc/php5/fpm/pool.d/www.conf) and uncomment the needed env[PATH] line.

Optionally update the content of the variable with the output of php -r "echo getenv('PATH');"

Solution 2

By default, PHP-FPM clears the environment variables (from the www.conf):

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

You can uncomment the last line to set clear_env to no, but if you prefer, you can set only the environment variables needed:

env[PATH] = $PATH

PATH is not cwd. My PATH looks like: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin‌​:/usr/games:/home/fo‌​ta/Development/adt-b‌​undle-linux-x86_64-2‌​0130917/sdk/platform‌​-tools

Sorry, I got confused. it seems like PATH is from linux, do you need to access the string directly or is it just a list of include folders? I've updated my answer to fit the latter in case.

Thank you for answer, but PATH variable will change from time to time and I didn't want to modify php.ini every time :( I'm sure there is a way to include bash's environment variable PATH.
