No environment variables are available via PHP-fpm+nginx - php

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]);

Answer 1

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

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');"

You could specify it via an include path: http://www.php.net/manual/en/ini.core.php#ini.include-path
You can specify it your php.ini (though you may want a specific path instead of including everything)
include_path=".:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/fo‌​ta/Development/adt-bundle-linux-x86_64-20130917/sdk/platform-tools "
