Installing Drupal

Hi.

I am new to Drupal and I am using the standard Drupal 8 install built in to the Synology packages software, which installed to use php 7.0.

Having seen a report from within Drupal suggesting moving to php 7.2, I installed php 7.2, again using the standard Synology package installation. This seems to have completed without error.

However, Drupal is still happily using PHP 7.0 ... How do I inform Drupal that it should now be looking to the php 7.2 install?

Thanks.

Drupal Version: 8.6.4

I've been working with Drupal since about 2012. I'll label myself as a solid "intermediate". I am currently using the MAMP environment; each site I am working on in its own folder in HTDOCS. This has worked well for me, however as I have branched into using Composer, I am seeing things like Drupal VM, Docker, Docksal, etc. 

I'm discovering drupal and I'm a little confused about installing an existing Drupal project. The existing project has been developed with Drupal and Symfony. I'm using Wamp and PHP 7.2.14.

I do the following steps for the installation:

Hello guys. I'm not that experienced in Drupal yet. But I have technical background in hardcoding. I need to adjust some features from the site. But first, I want to test it in local. I'm stuck at the installation of the existing site. I want to try it in XAMPP. Am I still in the right track?

I have the whole files of the file.
I have .sql of its database.

I'm using Windows and XAMPP. What I did was I put the folder of all files in htdocs. And I'm stuck in the database configuration at the installation.php.

I have on other website for several years used Drupal 7. Now i have to make a new site and will try Drupal 8. Installation went well, but when i see the site it is not very nice. It looks like the theme doesn't work. Does anyone have a suggestion :-)

Hello Everyone,

I had a functioning Drupal 8 site and decided to install Drupal Commerce. I followed the instructions to do so using composer. After installation, attempting to visit my homepage now redirects me to /core/install.php

Checking the error log gives me:
PHP Fatal error:  Cannot redeclare config_get_config_directory() (previously declared in /home/***/public_html/****/core/includes/bootstrap.inc:179) in /home/***/public_html/****/web/core/includes/bootstrap.inc on line 192
