Could someone give me a brief explanation of the “this” command, as I am utterly confused :frowning:

Thank you in advance for your response

There is no ‘this’ command.

$this is a special variable inside of a class definition. $this is used to refer to the instance of the object implicitly, without needing to know the instantiation name.

For example.


class HelloWorld {
  public $msg;

  function __construct($in) {
    $this->msg = $in;
  }
}

So, i’ve got a class. Named HelloWorld. When I create an instance of my HelloWorld object, I have to specify a message. This message could be anything, and can be different for each instance of HelloWorld.


$bunny = new HelloWorld("Bunnies are cool.");
$lion = new HelloWorld("Bunnies are tasty.");

Note that the class definition has no idea that i’ve named my object variables $bunny and $lion… and it doesnt care, either.


echo $lion->msg; //Bunnies are tasty.
