silly enough suggestion #3

Hello Josh,

In the pdo chapter pag 95/96 i would rather use:

// settings.php
return [
    'host' => '127.0.0.1',
    //....
];

and then set the variable including the file:

$settings = '../settings.php';

i think it's always preferable to have variables defined in the same file they are used (when possible).

kind regards,
great book!
:-)
