Module (trait)

Overview:

Module allows runtime extension of classes with new methods using closures.

Use the Module trait when you need runtime extension points, allowing modules to be augmented with new methods without editing class source.

Public API:

• ::extend($method, $callback = null) registers new methods.
• Magic call and callStatic dispatch to extensions.

Example:

Text::extend('shout', function ($s) { return strtoupper($s) . '!'; });
echo Text::shout('hello');

The Module trait provides a way to extend classes, even static with new methods.

Extend a class with new methods

class Test {
  use Module;
  public static function Foo(){ echo "Foo"; }
}

Test::Foo(); // Foo
Test::Bar(); // Fatal error: Call to undefined method Test::Bar

Test::extend([
  'Bar' => function(){ echo "Bar"; },
]);

Test::Bar(); // Bar
