PHP stuck

Extending from a parent class allows the child to inherit all attributes and abilities of the parent. Step 1: Add a new method to the Developer class named displayUserSkills. Step 2: Use the 'name' from the PARENT class, and the 'skills' from the CURRENT class, to replace the <PLACEHOLDERS> and RETURN following string (NOTE that skills separated with a comma and space): <NAME> has the following skills: <SKILL1>, <SKILL2>, <SKILL3> Example Output: Alena has the following skills: PHP, MySQL, HTML

my code so far:

<?php

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

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

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

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

}

}

$an_array = array("PHP","MySQL","HTML");

$stuff = new Developer ;

$stuff -> setSkills($an_array);

$stuff -> setName('Alena');

echo $stuff->getName() . " has the following skills: " . implode(', ', $stuff->displayUserSkills());

?>

Out put error;

Alena has the following skills: PHP, MySQL, HTMLPHP Warning: strtolower() expects parameter 1 to be string, array given in 37235294-194c-4d9b-943d-c20e202f54c4.php on line 224 Warning: strtolower() expects parameter 1 to be string, array given in 37235294-194c-4d9b-943d-c20e202f54c4.php on line 224

anyone knows why?

You don't need to display the output example. Here is my code for your reference.

<?php

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

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

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

  public function displayUserSkills()
  {
      return $this->name . " has the following skills: " . implode(", ", $this->getSkills());

  }

}

Hope this helps.

This worked for me!

<?php

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

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

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

  public function displayUserSkills() {
    return $this->name . " " . "has the following skills: " . implode(", ", $this->getSkills());
  }
}
