Question

Here’s the objective. I have a PHP class and there are one or two of its methods that I would like to override with my own. As I understand OOP (in PHP and in general) I could write a child class that extends it and overrides the functionality of the methods in question.

However, I was wondering if this is the best way of achieving this task and if this is a proper use for child classes or if there is something better in PHP for what I’m trying to do.

Answer 1

class oldClass {
  public function methodToOverride() {
    echo 'oh hai';
  }
}

class childClass extends oldClass {
  public function methodToOverride($arg, $arg2) {
    // your custom code
    echo 'hai world ' . $arg . ' ' . $arg2;

    // if you need to still call the parent class
    parent::methodToOverride();
  }
}

$child = new childClass();
$child->methodToOverride('nom', 'nom');
