4, mysqli_real_connect (): (HY000 / 2002): No such file or directory Error Handling

I just used the PHPStorm opened the phpmyadmin, clear the directory structure
as shown below, to directly copy config.sample.php config.inc.php
command line is no longer listed here! Not the point!
No such file or directory means that no config.inc.php this file!

Modify the following at 2
// $cfg['Servers'][$i][‘host’] = ‘localhost’;
//by wzh 20190629
$cfg['Servers'][$i][‘host’] = ‘127.0.0.1’;

// $cfg['Servers'][$i][‘password’] = ‘’;
// by wz h20190629 123456
$cfg['Servers'][$i][‘password’] = ‘123456’;

Test again
