向关联数组添加维度

Question

I have an array of default settings, that needs to be an associative array, it allows me to merge it with an array of settings saved in database:

$defaults = array ( 'eswc_redirect' => false,
                    'eswc_remove_shop_title' => false,
                    'eswc_remove_footer_credits' => 'Yes',
                  );

I would like it to store more parameters for the same settings, not just its value, for example type that I will later use to properly sanitize all the settings in a loop.

I expect to have over 50 settings and I need to make it as simple as possible, without double or triple typing the same. I would like to have everything related to a single setting written in one line like this (I expect it not to work, it's just to show my intent):

$defaults = array ( array ( 'eswc_redirect' => false, 'checkbox' ),
                    array ( 'eswc_remove_shop_title' => false, 'checkbox' ),
                    array ( 'eswc_remove_footer_credits' => 'Yes', 'text' ),
                  );

As a PHP novice, I would gladly see an example of how to access data from such an array in a loop.

I would also need to extract an array as presented in my 1st piece of code from this new array.

Answer 1

it would be better to keep it as an associative array, but make the values nested associative arrays.

$defaults = ['eswc_redirect' => ['value' => false, 'type' => 'checkbox' ],
             'eswc_remove_shop_title' => ['value' => false, 'type' => 'checkbox' ],
             'eswc_remove_footer_credits' => ['value' => 'Yes', 'type' => 'text' ],
    ];

Then you access it like $defaults['eswc_redirect']['value']

Answer 2

You can have many arrays in an array, for example:

$defaults = [
    'settings' => [
        'eswc_redirect' => false,
        'eswc_remove_shop_title' => false,
        'eswc_remove_footer_credits' => 'Yes'
    ],
    'database_connection' => [
        'host' => 'localhost',
        'user' => 'root',
        'pass' => ''
    ]
];

And you can easily access each configuration, for example:

$defaults['settings']['eswc_redirect']

and

$defaults['database_connection']['user']
