在PHP中使用Heroku配置变量？

Question

I am trying to get the heroku variable in PHP.I have been defined the variable in heroku.But the problem is I am not able to access those variable.

I have checked the variable in web and also console..The variable is there.But in PHP it shows empty.Anything need to be do in the composer or vendor?

In views file i tried like:

getenv('VIDEO');

But this is empty.Please help.

i already checked these links:

1. Use Heroku config vars with PHP?

2. https://devcenter.heroku.com/articles/deploying-php

Answer 1

There is Procfile in vendor/bin/heroku-php-apache2..If that file is there then that config var function works.

$config_var = getenv('CONFIG_VAR');

Sorry I was checking in localhost after clone from heroku.In localhost procfile file is not there.That is why that did not work.In heroku application that file exist.It works in heroku app.
