Create a public facing SETTER named "setSkills" that will accept an array and set the $skill property to that arrayvalue

class Developer extends User{ protected $skills=array();

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

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

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

//add new child class here
class Developer extends User{
  $protected $skills=array();

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

protected should not have a $ it should be

<?php
//add new child class here
class Developer extends User{

  protected $skills = array();

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

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

Your code is almost identical to mine, which was accepted as Task 2. (I'm looking only at the child class). I used the name $newSkills rather than $array as the input parameter. Might there be a problem with that name? What is the error message?

Btw, I came to this post looking to see if anyone was thrown off by the instruction to "set the $skill property", should be $skills.

Yes, "set the $skill property" confused me too!
