[php5버전이상] Method chaining / Fluent interface

개발하실때 도움될듯 합니다.

php로도 가능하네요.

핵심은 setter 메소드에 자기자신을 리턴하면 됩니다.

예제

class Person{
  private $_name;
  private $_sex;
  private $_age;
  private $_height;
  private $_weight;

  public function name($name){
    $this->_name = $name;
    return $this;
  }

  public function sex($sex){
    $this->_sex = $sex;
    return $this;
  }

  public function age($age){
    $this->_age = $age;
    return $this;
  }

  public function height($h){
    $this->_height = $h;
    return $this;
  }

  public function weight($w){
    $this->_weight = $w;
    return $this;
  }
  public function save(){
    $properties = get_object_vars($this);
    $str = '';
    foreach($properties as $property){
        $str .= $property.' ';
    }
    return $str;
  }
}

$p = new Person();
$res = $p->name('natura')->sex('Male')->age('99')->height('5.8')->weight('51')->save();
echo $res;

# natura male 99 5.8 51
