Php写错误

Parse error: syntax error, unexpected '$_SERVER' (T_VARIABLE) in /Users/Dima/Desktop/localhost/YouLose/lib/lib.php on line 17

什么事？在课外，它有效。在php $ _SERVER中我知道“超全球”

最好在构造函数中初始化它：

    public List<Users> GetUsers(string[] groupNames)
    {
        List<Users> employees = new List<Users>();
        string firstName = string.Empty;
        string lastName = string.Empty;
        string mail = string.Empty;

        using (var context = new PrincipalContext(ContextType.Domain,     "Name"))
        {
            foreach (var groupName in groupNames)
            {
                foreach (var userPrincipal in   GroupPrincipal.FindByIdentity(context, groupName).GetMembers())
                {
                    //code here please
                    employees.Add(new MPI.Domain.Entities.Users { First = firstName, Email = mail, Last = lastName });
                }
            }
        }
        return employees;
    }

类中的$ _SERVER ['DOCUMENT_ROOT']不起作用
