An Overview of Traits

  }
  // Gets the name of the runner
  // Must be implemented by the class using the trait.
  abstract public function name();

 * Define a class that uses the runner trait
 */

  use runner;
  // Used to store the person's name
  protected $name; // Constructor, assigns a name to the person

Changes to Anonymous Functions

$functions = array();
// assign an anonymous function to an array element
$functions['anonymous'] = function () {
  echo "Hello, the parser needs to make up a name for me...\n";
};
// to call it you had to do this:
$temp = $functions['anonymous'];
$temp();

// assume $functions[] is still around.
$functions['anonymous']();

Closures in Classes

value = $value;
  }

  public function getValue() {
    return $this->value;
  }

  public function getCallback() {
    return function() {
      return $this->getValue();
    };
  }
}

/**
 * Create a class that calls a closure.
 */
class ClosureCaller {
  private $callback;

  public function setCallback($callback) {
    $this->callback = $callback;
  }

  public function doSomething() {
    // Since this is a member variable, call Closure::__invoke().
    echo $this->callback->__invoke() . "\n";
  }
}

// Set up a class to generate closures that reference itself
$test = new ClosureTest();
$test->setValue(42);
$closure = $test->getCallback();
echo $closure() . "\n";

// Test calling a closure from another class
$testCaller = new ClosureCaller();
$testCaller->setCallback($test->getCallback());
$testCaller->doSomething();
