Yii2 routing when using CamelCase action names

Question

If you have say the following controller structure

Answer 1

I was thrown a little about this change too, but eventually I found it makes the URL easier to read. I was unsure about having a case sensitive route in Yii1, in Yii2 I do not have this problem (or impression of a problem) anymore.

I am not sure about the exact reason, but I can tell you that for SEO it is better to have - separating words instead of having 1 big word.

When I rewrote an application in yii2, I put in the url manager all the old routes that i need to maintain.

        'urlManager' => [
            'class' => 'yii\web\UrlManager',
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
.................................................
                'site/registerInterest' => 'site/register-interest',
.................................................

            ],
        ],

So my old links work now just fine. You can also put a 301 redirect in .htaccess if you want from the old routes to the new ones to keep the SEO juice.
