Symfony: Set External Parameters using PHP Built-In Server

[ryan0x44]

Hello,

I have found an issue with setting parameters externally (as explained on the "How to Set External Parameters in the Service Container" page) using PHP 5.4's built-in server.

If you refer to this StackOverflow question and this GitHub issue, you can see that the variables-order INI directive must be set to include "E" so that you can set environment variables like so:

export SYMFONY__DATABASE__PASSWORD="password"
php -d variables_order=EGPCS -S 0.0.0.0:8080 -t . test.php

This works fine, and SYMFONY__DATABASE__PASSWORD can be accessed via getenv('SYMFONY__DATABASE__PASSWORD') and $_ENV['SYMFONY__DATABASE__PASSWORD'].

The problem is,

• Setting env variables through Nginx will set them in $_ENV and $_SERVER
• Setting env variables through the built-in server will set them in $_ENV but _not_ in $_SERVER

The variables-order INI directive documentation contains the following warning:

"In both the CGI and FastCGI SAPIs, $_SERVER is also populated by
values from the environment; S is always equivalent to ES regardless
of the placement of E elsewhere in this directive."

The Symfony HttpKernel will only load the environment variables if they exist in $_SERVER, and not if they exist in $_ENV.
See the getEnvParameters() method in src/Symfony/Component/HttpKernel/Kernel.php.

If $_ENV was included in this method, I believe this would resolve the issue.
If there is an alternative solution, please let me know! :)

Cheers,
Ryan

a simple check php_sapi_name() == 'cli-server' in Kernel::getEnvParameters can be used to switch lookup from $_SERVER to $_ENV

Awesome thanks for the fix @fabpot!

Is there a reason why the server:run command does not allow to change php.ini settings using the PHP binary -d flag?

To work around the PHP issue with $_ENV/$_SERVER mentioned above I do not want to change my php.ini, I just want to do something like this:

SYMFONY__MY__PARAM=Foobar php -d variables_order=EGPCS -t web -S 127.0.0.1:8000 `pwd`/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/config/router_dev.php

I would prefer using server:run but I'm not able to pass the -d variables_order=EGPCS part.
