Wha? As in http request 'setMethod'? There's no particular reason why you'd use it there.

A method that will set a class property (variable). Getters are the opposite to setters, they get the value of a class property. Setters and getters are magic methods in php5 __set() __get() used for object overloading. Example:

<?php
class foo {
  private $data;

  public function __set($key, $val) {
     $this->data[$key] = $val;
  }

  public function __get($key) {
     return $this->data[$key];
  }
}
$x = new foo();
// set a value
$x->set('name', 'joe');
// get a value
print $x->get('name');
?>

Well, I'm not sure it could be explained any simpler.

 

Given your class with two properties, you simply need to make to seter methods to set each property.

 

class Div {
  
  private $nom;
  private $denom;
  
  public function setnom($amount)
  {
    $this->nom = $amount;
  }

  public function setdenom($amount)
  {
    $this->denom = $amount;
  }
  function do_it()
  {
    return $this->nom/$this->denom;
  }
}

$div = new Div;
$div->setnom = 100;
$div->setdenom = 50;
echo $div->do_it();
