About not displaying the change after editing the * .php file
I have the following application in heroku
https://heroku-magento-mozg.herokuapp.com/
Which has the following origin
https://github.com/mozgbrasil/heroku-magento
Using the following tool
https://heroku-magento-mozg.herokuapp.com/backdoor.php
I executed the commands to download and extract the following tool
https://github.com/kalcaddle/KodExplorer#install
Then using the following tool
http://heroku-magento-mozg.herokuapp.com/KodExplorer-master/index.php?editor
I edited the following file
https://heroku-magento-mozg.herokuapp.com/phpinfo.php
And I added script to display the value "214058"
After some time I tried to change to "21550"
But this change was not displayed
Today 15/02 in the access to phpinfo.php does not display any of the values but the original file
I have seen that this occurs according to the documentation
https://devcenter.heroku.com/articles/dynos#ephemeral-filesystem
My application uses Composer that downloads Magento and its dependencies
It turns out that in the installation step when reporting the database data is being returned error, then I would try to edit the Magento file as per the instructions
https://magento.stackexchange.com/questions/84782/database-connection-error-magento-installation
As my application repository does not have the Magento files since Composer is used how would I make this possible editing?
