plz help to child class function

Within the Client class, extend the constructor method from the parent to allow the company to be included with initialization.

User.php
<?php
//do not modify this file
class User {
    protected $name;
    protected $title;

    public function __construct($name = null, $title = null) {
        $this->name = $name;
        $this->title = $title;
    }

    public function __toString() {
        return $this->getSalutation();
    }

    public function getSalutation() {
        return $this->title . " " . $this->name;
    }

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

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

    public function getTitle() {
        return $this->title;
    }

    public function setTitle($title) {
        $this->title = $title;
    }
}
Developer.php
<?php
//do not modify this file
class Developer extends User 
{
  protected $skills;

  public function getSkills() {
      return $this->skills;
  }

  public function setSkills($array) {
      $this->skills = $array;
  }

  public function displayUserSkills() {
      return $this->getName() . ' has the following skills: ' . implode(", ", $this->skills);
  }
}
Client.php
<?php
//add code for Client class
class Client extends User{
private $company;
  public function getcompany() {
  return $this->company; 
    }
  public function setcompany($input) {
   $this->company = $input;
    parent::__construct(parent::getname(), parent::gettitle());
   }

}

class Client extends User 
{
  private $company = "";

  public function __construct($name = null, $title = null, $company = null) {
     parent::__construct($name, $title);
     $this->company = $company;
    }

  public function getCompany() {
      return $this->company;
  }

  public function setCompany($string) {
      $this->company = $string;
  }  
}
