Canonical url in laravel

You may set APP_URL in your .env file to https://example.com, then access it via

env("APP_URL", "somedefaultvalue");

Edit

You may consider create a helper to convert your URL

function addWwwToUrl($url) {

   $bits = parse_url($url);

   $newHost = substr($bits["host"],0,4) !== "www." ? "www." . $bits["host"] : $bits["host"];

   $newUrl = $bits["scheme"]. "://" . $newHost . (isset($bits["port"]) ? ":" . $bits["port"] : "" ) . (isset($bits["path"]) ? $bits["path"] : "" ) . (!empty($bits["query"])? "?" . $bits["query"]: "");

   return $newUrl;
}

Usage
