You cannot use a variable there, you have to transfer it to a method. This is bad style, as the User class needs to know about $ _SERVER.

If you really want this, you can use:

private static $signInURL = '';

public static getSignInUrl()
{
  if (User::$signInUrl == '') User::$signInUrl = $_SERVER....;
  return User::$signInUrl;
}


I suggest using:

class User
{
  private static $signInUrl = '/signin';

  public static getSignInUrl($base)
  {
    return $base . User::$signInUrl;
  }
}

You cannot put variables as the value of class properties. Try,



class a
{
 private $signInURL;
 public function __construct()
 {
  $this->signInURL = $_SERVER['DOCUMENT_ROOT'].'/?page=signin';
 }
}
