PHP Namespaces

Namespaces prevent class conflicts.

PocketMine heavily relies on namespaces.

---

Without namespaces:

class Player {}
class Player {}

Fatal error.

---

Namespace Example

namespace zyro\economy;

---

Class Example

namespace zyro\player;

class User {

}

---

Using Classes

use zyro\player\User;

---

Aliases

use pocketmine\player\Player
as PMPlayer;

---

Fully Qualified Name

\pocketmine\player\Player

---

Folder Structure

src/
└── zyro/
    └── Main.php

---

PocketMine Example

namespace zyro;

use pocketmine\plugin\PluginBase;

---

PSR-4

Namespace:

zyro\utils

Folder:

src/zyro/utils
