This sounds like a bad idea, so I'll just answer the actual problem of hardcoded domains. Fix this problem directly instead of applying more bandaid on top of a bad structure.

You should replace every occurrence of a hardcoded domain with a constant (using your text editors search/replace, not PHP), that you can switch however you like.

if (/* something */) {
    define('MYAPP_BASE_URL', 'http://example.com');
} else {
    define('MYAPP_BASE_URL', 'http://example2.com');
}

…

$url = MYAPP_BASE_URL;

Better yet, your code should be dynamic enough to be using $_SERVER['HTTP_HOST'] to begin with.
