J4 Get an array of parameters from template/module

Question

The current Joomla implementation looks like

$moduleHelper->getParams()->get('paramName'); // don't remember this one perfectly
$app->getTemplate(true)->params->get('paramName');

Is there a way I can get an array of all parameters? I need to get them in an array ready to filter based on certain specification, something like this:

(array) $moduleHelper->getParams()->get('*');
(array) $app->getTemplate(true)->params->get('*');

Please let me know. Thanks

I would use field groups instead of prefixes to organize fields in the form. This way no additional code is needed:

<fields name="params">
    <fields name="logo">
        <field
            name="src"
            type="media"
            default=""
            label="TPL_EXAMPLE_FIELD_LOGO_SRC_LABEL"
        />
        <field
            name="alt"
            type="text"
            default=""
            label="TPL_EXAMPLE_FIELD_LOGO_ALT_LABEL"
        />
    </fields>
    <fields name="colors">
        ...
    </fields>
</fields>

To get an object containing all values from logo group:

$params->get('logo');

Specific fields can be accessed using dot separated notation:

$params->get('logo.src');

Answer 2

I found an answer that explains the nature of the parameters and came up with a solution:

$app = Factory::getApplication();
$params = $app->getTemplate(true)->params;

$array_vars = array();
foreach(json_decode($params, true) as $k => $value) {
    if (strpos($k, 'my_setting_preffix_') !== false){
        $array_vars[$k] = $value;
    }
}

This is now exactly what I needed and the perfect solution to filter the outcome on the spot.
