How to detect multiple strings in $_SERVER["SERVER_NAME"]?

I would like to detect an array of strings in $_SERVER["SERVER_NAME"] to define a constant for environment like dev/prod.
Basically, if localhost or .dev is in the URL, that would set the constant to "prod".

Here is my try but I always got "prod" even if my current url is "localhost:3000" or "site.dev":

// Define environment
$dev_urls = array(".dev", "localhost");
if (str_ireplace($dev_urls, "", $_SERVER["SERVER_NAME"]) == $_SERVER["SERVER_NAME"]){
    define("ENV", "dev");
} else {
    define("ENV", "prod");
}

Finally used this code which works like a charm

// Define environment
$dev_urls = array(".dev", "localhost", "beta.");
if (str_ireplace($dev_urls, "", $_SERVER["HTTP_HOST"]) != $_SERVER["HTTP_HOST"]){
    define("ENV", "dev");
} else {
    define("ENV", "prod");
}

The SERVER_NAME is defined in the server config, it never changes no matter what URL you use to reach that page.

I believe you want to use HTTP_HOST instead.

if ($_SERVER['HTTP_HOST'] == 'localhost' || substr($_SERVER['HTTP_HOST'], -4) == '.dev')
    define('ENV', 'dev');
else
    define('ENV', 'prod');
