Answer 1

you just can create a function chain

class My_class
{

        public function method1($param)
        {
                /*
                 * logic here
                 */

                return $this;
        }

        public function method2($param)
        {
                /*
                 * logic here
                 */

                return $this;
        }

        public function method3($param)
        {
                /*
                 * logic here
                 */

                return $this;
        }

}

so you can use this

            My_class obj = new My_class();

            $return = obj->method1($param)->method2($param)->method3($param);
