class or function?

[jjmusicpro]

what is the difference?

 

 

[jjmusicpro]

i mean i can use either or right? just classes can be made abstract etc.

A lot of things, a class is an object with its own state and actions

 

class Dog {
  public $size;

  public function bark() {
     if($this->size == 'small') {
        echo "yipp!";
     } else {
        echo "woof!";
     }
  }
}

$dog = new Dog();
$dog->size = 'large';
$dog->bark(); // Outputs "woof!"
$dog->size = 'small';
$dog->bark(); // Ouputs "yipp!"

And this is just a tiny tiny tiny bit of what classes can do, they can inherit from each other, call each other, interact, etc.

 

functions are just a set action.

function doStuff() {
  echo "I'm doing stuff!";
}

doStuff(); // Outputs "I'm doing stuff!"
