Save Plugin Options as Array

Okey I got it. I was close the whole time 🙂

function weborder_leveranstext_render(  ) {

$options = get_option( 'weborder_settings' );
    
global $wp_roles;
$all_roles = $wp_roles->get_names();

foreach ($all_roles as $role => $value) {
    echo '<br><span style="width: 180px; display: inline-block;">' . $value . '</span>';
    echo '<input type="text" style="width: 300px;" name="weborder_settings[weborder_leveranstext]['.$role.']" value="'.$options['weborder_leveranstext'][$role].'">';
}

}
