 AFAIK \n is only processed inside double-quoted strings and here-docs. The

 My guess is the same as Adam's. Since I don't see how you declare
 INotification, I think it's getting confused when using namespaces. In the
 top part, PHP assumes the class must be in the org\puremvc\php\interfaces
 namespace whereas in SimpleCommand's declaration, INotification is assumed
 to be in the org\puremvc\php\patterns\command namespace. This causes their
 declarations to be mismatched.

Hi David,

It was a CNP error from several files that's how the INotification got
left out on the e-mail.  You're right.  I've must had a brain fart
yesterday afternoon.

Thanks,
Tommy

[PHP] possible namespace bug?

[Tommy Pham]

Hi folks,

I thought I try implementing namesapce on one the ported apps I did a while
back but ran into a problem.  First the code:

//namespace org\puremvc\php\interfaces;

interface ICommand
{
function execute(INotification $notification);
}
interface INotifier
{
function sendNotification($notificationName, $body = null, $type =
null);
}
//--
---
//namespace org\puremvc\php\patterns\observer;
//use org\puremvc\php\interfaces\INotifier;

class Notifier implements INotifier
{
public function __construct() { echo __METHOD__; }
public function sendNotification($notificationName, $body = null, $type
= null)
{
}
}
//--
---
//namespace org\puremvc\php\patterns\command;
//use org\puremvc\php\interfaces\ICommand;
//use org\puremvc\php\interfaces\INotifier;
//use org\puremvc\php\patterns\observer\Notifier;

class SimpleCommand extends Notifier implements ICommand, INotifier
{
public function __construct() { parent::__construct(); echo ' - ';
echo __METHOD__; }
function execute(INotification $notification) { }
}

//--
---
//echo 'br/'; new \org\puremvc\php\patterns\observer\Notifier();
//echo 'br/'; new \org\puremvc\php\patterns\command\SimpleCommand();


The above works as expected without namespace.  When I uncomment the lines
namespace/use, I get this error:

Fatal error: Declaration of
org\puremvc\php\patterns\command\SimpleCommand::execute() must be compatible
with that of org\puremvc\php\interfaces\ICommand::execute() on line 30.

Line 30 is the class SimpleCommand declaration.  Anyone having similar
problems?  My platform is PHP 5.3.5 VC9 NTS as FastCGI on Win08r2 x64.

Thanks,
Tommy

Where's the INotification namespace?  If it's in org\puremvc\php\interfaces,
you'll have to include it, too.  I see you just included the whole set of
interfaces in the top part of the example.  Maybe you just omitted the code,
but that could be the problem.
