Declares values on objects and output the values - php

Question

I need some guide or reference on how should I do this.
What I should do is, have a class structure named Cat and have a static method that outputs new object.
class Cat{
public $name;
public $age;
public $string;
static public function ToData($Cat) {
$input = "";
foreach ($Cat as $key => $value) {
$input .= "object: " . $key . "</br>";
}
return $input;
}
}
$name = "meow";
$age = "12";
$string = "'test', 'sample', 'help'";
$Cat = array($name, $age);
$output = Cat::ToData($Cat);
echo $output;
This is the best thing that I can come up with
here is the problem, they said I just used an array and not an object.
I used array because I have to put the values on the $Cat so it can be passed on the parameter.

Answer 1

Looks like it's an assignment on object-oriented programming concept in PHP. I believe this is what you're trying to accomplish, with comments explaining the steps.
class Cat{
public $name;
public $age;
// Output the attributes of Cat in a string
public function ToData() {
$input = "";
$input .= "object: name :".": ".$this->name." </br>";
$input .= "object: age :".": ".$this->age." </br>";
return $input;
}
}
$name = "meow";
$age = "12";
// Instantiate Cat
$Cat = new Cat();
$Cat->name = $name;
$Cat->age = $age;
// Output Cat's attributes
$output = $Cat->ToData();
echo $output;

Answer 2

if you want to set those values to the object here is what you do
...
foreach ($Cat as $key => $value) {
$this->$key = $value;
}
...
$name = "meow";
$age = "12";
$Cat = array("name"=>$name,"age"=> $age);
$cat = new Cat();
$cat->toData($Cat);
echo $cat->name;
// meow
Update:
Now i get a better idea what you are trying to do, this is how your class will look like:
class Cat{
public $name;
public $age;
public $string;
static public function ToData($Cat) {
$obj = new self();
$obj->name = $Cat["name"];
$obj->age = $Cate["age"];
$obj->string = $Cate["string"];
return $obj;
}
// echo
public function __toString(){
return "$this->name - $this->age - $this->string";
}
}
now you can set your values
$name = "meow";
$age = "12";
$string = "'test', 'sample', 'help'";
$Cat = array($name, $age,$string);
$output = Cat::ToData($Cat);
echo $output;
Note that $output is an object
