I'm parsing the code of the SKU generator module, I can't understand why we need an array with urls and what's going on there?

Question

opencart

code from generator sku controller file
/* Set urls */
$data['urls'] = array();
$data['urls']['generateAllSku'] = $this->url->link('extension/module/sku_generator/generateallSku', 'token=' . $this->session->data['token'] , true);
$data['token'] = $this->session->data['token'];

Answer 1

A link is created to generate Sku for all products.
