Symfony2 custom console command appears as “not defined” upon execution - symfony

Please help, I've tried everything;
The command works well on the development server, but not on live.
Before you mark it as duplicate:
The filename ends with Command.php
The Bundle is registered
The command is ContainerAware
The command is in the Bundle\Command directory and in the App\Bundle\Command namespace
I have tried:
clearing and warming up the cache on the server multiple times using the symfony console php console --env=preprod cache:clear and php console --env=preprod cache:warmup
listing available commands by calling the console without extra arguments php console --env=preprod
Is there any other way to force symfony to re-check available commands ?

For future reference:
The problem was that I connected to the remote host before deploy, and bash doesn't update symlink targets.
So the Command was not available in my current working directory.
A simple cd .., cd current solved it.

Composer scripts disregards Symfony console environment variable

I am facing an issue where the build process of my Symfony application fails, as explained in many different forums (none recent). For instance:
When doing composer install with --no-dev only the production packages
are installed (as it should be). However when composer launches the
symfony scripts they are launched in development modes and thus start
throwing errors when AppKernel.php can not find packages needed for
development. These scripts should also be executed in production mode!
Quote source
The above Github issue is closed, as it apparently can be fixed by setting the SYMFONY_ENV env variable to the environment of your choice: export SYMFONY_ENV=prod.
I have done that, and calling printenv correctly prints the variable. I can even call the Symfony console php bin/console manually. and it will launch in prod environment.
Success? Seemingly, but no... Calling composer install still forces all scripts to launch in dev environment. What gives?
The root cause appears to be the environment variable not being set globally, so whatever user the commands ended up running as, www-data via my deploy script, or root(as I called sudo composer?) from the console, did not have the environment variable set that I created with my default user.
Adding SYMFONY_ENV=prod on a new line in /etc/environment, and then restarting fixed the issue, and the scripts are now running in prod.

How to use/enable PHP extensions for CLI on swisscomdev/cloudfoundry php_buildback?

** EDIT **
For several cases we need to call Symfony commands on a deployed CloudFoundry app. Symfony commands are php scripts which are called with the PHP CLI.
One example is bin/console doctrine:schema:update (but could be user generation, cache clearing etc.)
So for our app we need both, fpm and cli enabled. This is done with:
"PHP_MODULES": [
"fpm",
"cli"]
in options.json.
After connecting to the app with cf ssh I change to app directory and I call php/bin/php doctrine:schema:update this results in a ClassNotFound: PDO issue.
During staging these commands are called successfully.
I checked that for PHP CLI the PDO extension is not available (by checking php -i) although I have mentioned it in options.json.
"PHP_EXTENSIONS": [
...
"pdo",
"pdo_mysql",
...]
How to enable extensions for CLI and FPM on one app? And is it theoretically possible to have different extensions for CLI and FPM and as well different user-php.ini s to fully/particularly override php.ini of CLI and FPM?

This is something that we should probably clean up in the build pack. I do not believe it's (PHP_MODULES) actually used any more.
Maybe a year or more ago, the build pack switched how it downloads PHP. It would previously download individual components modules & extensions. Now it just downloads everything at once. This actually ends up being faster since it's one larger download vs many smaller downloads, and bandwidth is generally very fast for build pack downloads.
Worth mentioning that while PHP_EXTENSIONS no longer triggers what to download it is still used in terms of what extensions get enabled in php.ini. Thus you still need to set that or indicate extensions through composer.
After connecting to the app with cf ssh
I believe that this is the issue. You need to source the build pack env variables so that the env is configured properly.
Ex:
vcap#359b74ff-686c-494e-4a1e-46a9c420f262:~$ php
bash: php: command not found
vcap#359b74ff-686c-494e-4a1e-46a9c420f262:~$ HOME=$HOME/app source app/.profile.d/bp_env_vars.sh
vcap#359b74ff-686c-494e-4a1e-46a9c420f262:~$ php -v

Staging does this automatically as does runtime for your app. Unfortunately cf ssh does not.
UPDATE:
A slightly easier way to do this is to run cf ssh myapp -t -c "/tmp/lifecycle/launcher /home/vcap/app bash ''". This will open a bash shell and it lets the lifecycle launcher handle sourcing & setting up the environment.
And is it theoretically possible to have different extensions for CLI and FPM and as well different user-php.ini s to fully/particularly override php.ini of CLI and FPM?
Sure. By default, we download and install all extensions. Thus you just need a different php.ini (or some other setting to enable that extension) in which you enable your alternate set of extensions.
When you cf ssh into the container, you could copy the existing php.ini somewhere else and edit it for your CLI needs. Then reference that php-alt.ini when you run your CLI commands.
Never did this but does enabling the php cli in PHP_MODULES (https://docs.developer.swisscom.com/buildpacks/php/gsg-php-config.html) help?

How to permanently resolve Symfony2 twig_upper_filter error?

Situation:
Production mode
Change a file
One of the pages on the site returns the following 500 internal error.
Run composer update, and the error goes away.
Change a file and the problem returns.
The code calling the twig_upper_filter is buried deep inside the now embedded in symfony bootstrap templates.
What does composer update do that might fix this? It is repeatable (on one server only).
UndefinedFunctionException: "Attempted to call function
"twig_upper_filter" from the global namespace." at
Symfony 2.6.
Because at the end of composer update it does a cache clear, everytime you change something somewhere you need to clear the cache for the change to be visible in the production enviroment.
This is automatic on the development enviroment.
You need to run this from console:
cd /your/symfony/app
php ./app/console cache:clear --env=prod
Letting the web server build the cache resolved the problem. The command line environment must not be exactly the same as the web server php. On this server it is difficult to actually run command line scripts as the web server user.
Therefore, clearing the cache on the command line with no warmup is the work around:
php ./app/console cache:clear --no-warmup --env=prod

Symfony in wamp error: Could not open input file: ⌠E:\wamp\bin\php\php5.5.12\symfony÷

I just installed symfony in my wamp according to the tutorials in below websites
http://uniapple.net/blog/?p=298
http://uniapple.net/blog/?p=298
all had finished without any error. But after finished all, when give the command symfony in cmd, it shows the below error.
Could not open input file: ⌠E:\wamp\bin\php\php5.5.12\symfony÷
and i couldn't figure it out. Please help..
Thank u in advance
If you are trying to use the Symfony console, you need to be in CMD and go to your project root:
cd C:\Sites\project
Before you try any commands, please make sure PHP is in your PATH variable.
Then to do commands in symfony you need to do:
php app/console command:action
//for example, do a cache warmup - choose your environment
php app/console cache:warmup --env=[dev|prod]
Is this what you mean when you want to use Symfony in cmd?

Symfony2 Composer Install

I am trying to install Symfony 2.1.3 (latest). I am running composer and installs everything okay. The only error that I get is:
Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache
handling the post-install-cmd event terminated with an exception
[RuntimeException]
An error occurred when executing the "'cache:clear --no-warmup'" command.
It's being installed under www folder. I am running nginx and followed the composer approach. I read on internet that apache should be run manually not as a service, however I am using nginx instead. Does apache still have any bearing on it? I'm using debian squeeze.
Edit: As per AdrienBrault's suggestion the error was because the timezone was not set in the php.ini. Only with --verbose I could see the warning. Thanks guys.
Apache is not related - PHP is called via command line.
Most likely is the permission in the cache folder: did you check if the user that runs the composer update can actually write the cache folder?
Try to manually run rm -Rf app/cache/dev (for production environment replace dev with prod) and see if you get any permission error.
Also you will get this error if the default.timezone setting is not configured in php when running in CLI. To verify just run
php --info | grep timezone
and check that the setting date.timezone is correctly configured.
On the security side, setting 777 to the folder is not the optimal solution - if you have ACL enabled you could use that to correctly set up the permission for the cache and logs folder. Read more at the Symfony2 official installation page
I had this same issue for a while and after hours of face to brick wall pounding I realized... I have a .gitmodule in my project, and on initial checkout these submodules are NOT initialized and as such are not there for your composer to update, which results in the above error.
Make sure you run the following
git submodule update --init src/Acme/Sadness/Bundle
of course replace src/Acme/Sadness/Bundle with YOUR project namespace.
Hope this helps someone not go through the same pain I just did.
If you have vendor folder already I would remove it and install symfony 2.1.3 again via "composer.phar install". Problem might be coming from outdated version of composer
I had the same problem and I resolve in this way.
execute this on the console
and you should see something like this
$ locate php.ini
/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini
/etc/php5/fpm/php.ini
the first line is probably your php.ini that appear when you do a phpinfo();
the problem is that when you execute composer update this no check the same php.ini
in my case the second line
all my sites work fine but always I had problems not now
after edit the second file and put the same time zone that you set in the first one
run
$ sudo service apache2 reload
and now
$ composer update
I hope that this work for you like work for me
regards
Emiliano
