Codeigniter with PHP 7 on MAMP - Troubleshooting

I had codeigniter app that was running well with PHP 5.6 on MAMP.

I got the latest version of MAMP Pro with the latest PHP 7.

Everything was fine, till I browsed to my CI app.

It wouldn't load!!

After a bit of troubleshooting, I figured that a small change had to be done in my database.php configuration.

I changed 'dbdriver' => 'mysqli' to 'dbdriver' => 'mysqli' and everything worked smoothly thereafter!

Woof!
