I am having an issue with trying to set environment variables in my EC2 instance and then retrieving them with php.
So I have an EC2 instance running a Bitnmai Wordpress site. I ssh's into the server and added the environment variable in
/etc/environment
export VARIABLE_NAME=example_value
on the front end of things, my php to retrieve the value is:
<?php $env_var = $_ENV["VARIABLE_NAME"];
But it returns blank
I have also tried
$env_var = array('environment' => getenv("VARIABLE_NAME"));
But that just returns {environment: false}
Any help would be greatly appreciated
I typically set environment variables on EC2 instances in an .htaccess file. For example, here is MySQL connection information which is consumed later by a configuration file:
SetEnv DBL "mysql:dbname=rocknroll;host=rocknroll.local;port=3306"
SetEnv DB_USER "Elvis"
SetEnv DB_PASS "1amth3K1ng"
Then in my PHP file(s) I do this:
define('DBL', getenv('DBL'));
define('USER', getenv('DB_USER'));
define('PASS', getenv('DB_PASS'));
This uses PHP's getenv() function and makes the variables easy to retrieve.
So when I would restart the apache server, it would overwrite the .htaccess file to its default state and all my changes would be gone.
So I found a solution that works for what I need. I added the environment variables into the wp-config.php file define('ENV_VARIABLE','VALUE');
Then I was able to use that value by $value = ENV_VARIABLE;
Thanks for all of the help!

I am running Drupal sites (Apache and PHP), and would like to set some of the values in the settings files to be environment variables. After researching, the proper approach appears to be adding them into the /etc/sysconfig/httpd file. It appears that PHP (mod_php) is not loading the variables.
My /etc/sysconfig/httpd file looks like this -
LANG=C
db_server=internaldns.mine.com
db_port=3306
memcache_server1=otherinternaldns.mine.com:11211
I am loading the variables in Drupal (which is php 7 (mod_php)) like this -
$databases['default']['default'] = array (
...
'host' => $_ENV['db_server'],
'port' => $_ENV['db_port'],
...
);
However, it doesn't appear to be loading the variables, as when I do a status of the site, I see the following -
Drupal version : 8.9.11
Site URI : http://default
DB driver : mysql
DB port : (THIS SHOULD HAVE THE VARIABLE)
When I set the same values without variables they work normally.
Is there some step I am missing here for getting the variable loaded inside of the env?
To anyone who encounters something similar:
Even though the variables were set in the /etc/sysconfig/httpd file, they were not being imported into my Shell (but PHP was importing them correctly).
After creating a file in /etc/profile.d/ that exported the variables for the shell, it worked on the cmd line as well -
#!/bin/bash
# DB Vars
export db_server=db_server
export db_port=3306
As a note - Even though it looked like a failure on the CMD line before these variables were exported, the website was being served successfully by httpd. This implied that PHP was using the variables correctly.
Laravel has a .env file that contains various variables. Is there a way to get all the variables in one line of PHP code? I don't want to write
echo env('APP_DEBUG')
echo env('APP_URL')
etc...
I have tried
env("*")
env("*")
but none works.
This should work:
$_ENV; // gives all env variables.
To get a single env variable:
$_ENV['VARIABLE'];
The only safe way for reading all env() attributes is to use Dotenv directly :
$env = Dotenv\Dotenv::createArrayBacked(base_path())->load()
This method is usable on every environment : cli, dispatched jobs, without proper web server and even if php.ini is ignoring env.
I'm trying to set multiple cloud servers behind an ALB to write their log files to my common EFS. I have a single shared drive EFS, which I can access via a single development instance, while all my production instances are securely behind a VCN. I am trying to use system environment variables (specifically the HOSTNAME) so that each of the production instances, which use the same configuration file to start php-fpm (so that I can do auto-scaling), write a different log.
I've seen answers that say that the *nix way of using environment variables should work, but they are not working for me. Specifically ${HOSTNAME} returns blank (and I have checked it is set for the apache and root users; root starts the php-frm service). I also tried interpolations of that, and the bash flavor of things "%()". None of them work.
All of them return blank strings (but not errors).
I did create a single variable in my environment variable, and got that to work.
I also read that you can't assign a env value to a variable directly, but when I tried to create a separate variable, that actually returned an error when starting the service.
This is what I would expect to work:
slowlog = "/shared/logs/php-fpm/www-slow-${HOSTNAME}.log"
Tried all of the following:
slowlog = "/shared/logs/php-fpm/www-slow-".${HOSTNAME}.".log"
--> blank for hostname
slowlog = "/shared/logs/php-fpm/www-slow-${HOSTNAME}.log"
--> blank for hostname
slowlog = "/shared/logs/php-fpm/www-slow-%(HOSTNAME).log"
--> the file name includes %(HOSTNAME)
slowlog = "/shared/logs/php-fpm/www-slow-$HOSTNAME.log"
--> the file name includes $HOSTNAME
slowlog = "/shared/logs/php-fpm/www-slow-{$HOSTNAME}.log"
--> the file name includes {$HOSTNAME}
slowlog_name = "/shared/logs/php-fpm/www-slow-{$HOSTNAME}.log"
slowlog = slowlog_name
--> start error: unknown variable slowlog_name
Thank you for any tips/advice!
PHP 7.3 does support environment variable interpolation for log file names in config files - I just tested this. I suspect that where you're getting caught is that in bash, $HOSTNAME is a bash variable but not automatically an environment variable, and Linux systems vary in whether $HOSTNAME is set as an environment variable. RedHat distros do set it, Ubuntu does not:
jacob#nitrogen ~ $ cat /etc/redhat-release
Fedora release 29 (Twenty Nine)
jacob#nitrogen ~ $ echo $HOSTNAME
nitrogen
jacob#nitrogen ~ $ env | grep HOSTNAME
HOSTNAME=nitrogen
jacob#iad11:~$ grep PRETTY_NAME /etc/os-release
PRETTY_NAME="Ubuntu 18.04.2 LTS"
jacob#iad11:~$ echo $HOSTNAME
iad11
jacob#iad11:~$ env | grep HOSTNAME
You can test with a different environment variable, and then set $HOSTNAME in a custom startup script that then starts PHP.
I have a php app into heroku. I use the free version. My app use codeigniter framework and I need ignore some files with a gitignore, for example I have a file database.php with the information of the database connection's. That information is different in each enviroment, my question is, how can upload these kind of files into heroku?
This is the wrong way to solve your problem. Any config information like:
api keys
database host / password
any other specific env configuration
shouldn't be versionned in git.
You should use environment variables. I assume you want to use different database host/username/password whether you're in development environment (your working directory), in staging, or in production.
1) Check how to set environment variables (it's different between Windows and Linux/Mac OS X), but you have helpers and it's a good practice to use that (even more when using heroku)
2) Since you're using php, you'll be able to retrieve those variable with getenv. You should have something like :
$dbUserName = getenv('DB_USER_NAME');
$dbHost = getenv('DB_HOST');
$dbPassword = getenv('DB_PASSWORD');
//use the variables above to make a db connexion
3) Time to set the env variables on your heroku vm (see more)
$ heroku config:set DB_USER_NAME=foo
$ heroku config:set DB_HOST=bar
$ heroku config:set DB_PASSWORD=fee
Your code will automatically use the correct config when you'll push to heroku (you won't have to bother to have to change something on your code base between your dev env and your production env + each team member can have different config on their local dev machine)
I'm using AWS Beanstalk which allows me to set environment properties in the backend for my application container and retrieve theme as shown below:
echo get_cfg_var('aws.access_key');
echo get_cfg_var('aws.secret_key');
echo get_cfg_var('aws.param1');
echo get_cfg_var('aws.param2');
I'd like to set up a similar environment property locally, so that my password never reach my repository (I'm using git) - what is the best way to do this? php_ini? httpd.conf? How would I add the variable param1 = 'password';?
Cheers!
in your php.ini add the lines.
aws.param1=whatever
aws.param2=whatever
