PHP DateTime class Namespace

Question

I'm using the symfony2 framework and I want to use the PHP's DateTime class (PHP version is 5.3).

Here the declaration:

namespace SDCU\GeneralBundle\Entity;  class Country {    public function __construct(){        $this->insertedAt = new DateTime();    } } 

But, when executing this constructor, I get an error saying that there's no "SDCU\GeneralBundle\Entity\DateTime" class. I've been searching around for DateTime's namespace but with no success... any idea?

Answer 1

DateTime is in the global namespace, and as "class names always resolve to the current namespace name" you have to use \DateTime.

Or import the package using:

use \Datetime; 

Answer 2

Better solution for using classes in global namespaces is "use" keyword instead of "\" before class.

namespace SDCU\GeneralBundle\Entity; use \DateTime;  class Country {    public function __construct(){        $this->insertedAt = new DateTime();    } }
