回答1:

Is your PHP environment the same as your browsers PHP? command line php.ini can differ from, for example, your XAMP or other installed webserver

I would recommend checking this first

for me this did the trick

edit your .bash_profile file like

export PATH=/Applications/MAMP/bin/php/php7.1.1/bin:$PATH

edit the path to your PHP bin from your XAMP

In my case I got similar error

Warning: mysqli_connect(): (HY000/1049): Unknown database 'login.db' in D:\xampp\htdocs\login\functions\db.php on line 2 so i change [$con=mysqli_connect('localhost', 'root', '', 'login.db');] into [$con=mysqli_connect('localhost', 'root', '', 'login');]

Ii changed 'login.db' to 'login' and error disappear

If you have this code:

$conn = new mysqli("localhost", "root", "", "myDB");

Try with creating new database called myDB in localhost/phpmyadmin.
