How to use PHP 5.6 / 7 with PHPBrew, but not just in CLI?


I’m trying to achieve a setup where I can easily switch the frontend (not CLI) PHP version with PHPBrew between 5.6 and 7 whenever. For now, I’ve only achieved that the bash has the 5.6.31, the frontend phpinfo() says PHP Version 5.5.9-1ubuntu4.17 which is obviously something I don’t want to see. I’ve already managed to do this on another workspace where it says PHP Version 5.6.31, but I’m afraid to touch that workspace to venture into trying to switch to PHP 7. I have no idea how I achieved to make the PHPBrew version the system level PHP…

I’ve read the related topics but they aren’t helping me. This is how I set it up for now:

curl -L -O 
chmod +x phpbrew
sudo mv phpbrew /usr/local/bin/phpbrew
phpbrew -v
phpbrew init
echo '[[ -e /home/ubuntu/.phpbrew/bashrc ]] && source /home/ubuntu/.phpbrew/bashrc' >> ~/.bashrc 

sudo apt-get update
sudo apt-get install apache2-dev
sudo apt-get install libcurl4-gnutls-dev
sudo apt-get install libmcrypt-dev libreadline-dev
sudo phpbrew install php-5.6.31 +default +dbs +mb +iconv +apxs2=/usr/bin/apxs2

Please note that I have no earthly idea what I’m doing, I never used Linux. I just collected these lines from threads like this and they looked promising, but I must be missing something.
