PHP 7:

In addition to creating an additional property ($dog_gender) and set method in the Dog class, create method to display the updated values. Also update the lab.php file to include a print statement (similar to the examples in this section) to call the get methods.

Dog.php:

class Dog

{

// ----------------------------------------- Properties -----------------------------------------

private $dog_weight = 0;

private $dog_breed = "no breed";

private $dog_color = "no color";

private $dog_name = "no name";

// ---------------------------------- Set Methods ----------------------------------------------

function set_dog_name($value)

{

$error_message = TRUE;

(ctype_alpha($value) && strlen($value) <= 20) ? $this->dog_name = $value : $error_message = FALSE;

return $error_message;

}

function set_dog_weight($value)

{

$error_message = TRUE;

(ctype_digit($value) && ($value > 0 && $value <= 120)) ? $this->dog_weight = $value : $error_message = FALSE;

return $error_message;

}

function set_dog_breed($value)

{

$error_message = TRUE;

(ctype_alpha($value) && strlen($value) <= 35) ? $this->dog_breed = $value : $error_message = FALSE;

return $error_message;

}

function set_dog_color($value)

{

$error_message = TRUE;

(ctype_alpha($value) && strlen($value) <= 15) ? $this->dog_color = $value : $error_message = FALSE;

return $error_message;

}

// ----------------------------------------- Get Methods ------------------------------------------------------------

function get_dog_name()

{

return $this->dog_name;

}

function get_dog_weight()

{

return $this->dog_weight;

}

function get_dog_breed()

{

return $this->dog_breed;

}

function get_dog_color()

{

return $this->dog_color;

}

function get_properties()

{

return "$this->dog_weight,$this->dog_breed,$this->dog_color.";

}

}

?>
