PHP Method Chaining

Method chaining, also known as named parameter idiom, is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results

/*
* ChainableClass
* cascading-by-chaining by returning this
*/
class ChainableClass {
  function methodOne() {
    echo __METHOD__.' called, ';
    return $this;
  }
  function methodTwo() {
    echo __METHOD__.' called';
    return $this;
  }
}
(new ChainableClass)->methodOne()->methodTwo();
// Result: BaseClass::methodOne called, BaseClass::methodTwo called

With Static

/*
* ChainableClass
* cascading-by-chaining by returning self
*/
class ChainableClassStatic {
  public static $prop;

  public static function ChainableStaticMethod()
  {
    self::$prop = 'Chainable Class String';
    return new self;
  }

  public function regularMethod()
  {
    echo self::$prop;
  }
}
ChainableClassStatic::ChainableStaticMethod()->regularMethod();
// Result: Chainable Class String
