Creating rules in urlManager in Yii2?

Question

Yii

Let's say there is such a link,
" http://mysite.com/site/sub?al=villas-and-houses "
I want to see " http://mysite.com/villas-and-houses " when I go to it,
wrote this rule, but there is one but, it works where there is one word in the get parameter or is separated by an underscore, and where there is a hyphen it does not want to work, how can I make it work with a hyphen?
'' => 'site/sub',

Answer 1

'urlManager' => [
            'class' => 'yii\web\UrlManager',
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                '<al>' => 'site/sub'
            ]
        ],

'<al:[\w-]+>' => 'site/sub'
