Save Plugin Options as Array

I am trying to create a simple option page. The options consist of a text field per user role. But I don't want to edit the code every time I add a new user role.

So I am trying to for each- user roles and build text fields from it. But the value does not get saved in the options. I think I need to save the values in an array before save.

Like this:

add_settings_field( 
'weborder_leveranstext',
__( 'Header', 'weborder' ), 
'weborder_leveranstext_render', 
'pluginPage', 
'weborder_pluginPage_leveransalternativ'

);

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 'input type=text name=?? value=' . $options['weborder_leveranstext'] . '';
   }
}

I have tried a lot of thing but I think that this must be saved in array. I have tried similar thing to this without success:

echo 'input type=text name=weborder_leveranstext_'.$role.' value=' . $options['weborder_leveranstext_'.$role.''] . '';
