I am following this tutorial to set up wordpress locally with Mamp on https://codex.wordpress.org/Installing_WordPress_Locally_on_Your_Mac_With_MAMP
Holding by step 3:
Step 3: Starting MAMP Servers & Creating The Database To start the MAMP Apache and MySQL servers, simply click "Start Servers" from the main MAMP screen. Your MAMP servers have now been started.
Once the MAMP servers start, the MAMP start page should open in your default web browser. If not, click on "Open start page" in the MAMP window. Once that's open, select phpMyAdmin from the webpage.
Under "Create new database", enter in a database name such as "wordpress", and press "Create." No need to choose an option for "collation" : it will automatically be assigned by MySQL when the database tables are created, during the WordPress installation.
I can't get into PHPMyAdmin because it requires PHP 5.5.X - 7.0.X and I have PHP Version 7.1.1.
I tried looking online how to downgrade, and I am afraid I will break everything as this is my first time doing this.
Any help is muchly appreciated.
