Bug #54309 Multiple environment variables for PHP_ADMIN_VALUE only accepts last value
Submitted: 2011-03-18 17:31 UTC Modified: 2011-07-02 12:55 UTC

Description:
------------
If you wanted to specify multiple PHP_ADMIN_VALUE environment variables, such as 
(nginx config):

fastcgi_param PHP_ADMIN_VALUE "sendmail_from=Me";
fastcgi_param PHP_ADMIN_VALUE "sendmail_path=/usr/sbin/sendmail -f me@me.com";

then only the second one gets picked up (probably because as an environment 
variable, the last one is clobbering over the first one(s)).



Expected result:
----------------
Respect multiple PHP_ADMIN_VALUE variables, or perhaps read in environment 
variables like PHP_ADMIN_VALUE[variable_name], so that this would work:

fastcgi_param PHP_ADMIN_VALUE[sendmail_from] "me";
fastcgi_param PHP_ADMIN_VALUE[sendmail_path] "/usr/sbin/sendmail -f me@me.com";

This is not a problem related to PHP. In fact this is due to the fastcgi 
protocol specification: only one parameter with the same name is allowed. If you 
try to set more than one parameter with the same name, the behaviour depends on 
the fastcgi client implementation (nginx only sends the last one)

The solution is to merge everything into one header separating with \n. 

fastcgi_param PHP_ADMIN_VALUE 
"sendmail_from=Me\nsendmail_path=/usr/sbin/sendmail -f me@me.com";
