4,778 PointsThe read it's mean that you can access/see the property directly within class. The write it's mean that you can set the property directly within class. for example
class instance
{
//property
public $number = 5;
}
$a = new instance();
$a->instance = 10; // you can write/set directly property number
echo $a->instance; // you can read directly property number
Otherwise you can access directly property $number if the visibility is private.
class instance
{
private $number = 5;
// you must using this to read variable $number
public function getNumber()
{
return $this->number;
}
}
$a = new instance();
$a->instance = 10; // you can't write/set directly variable number (wrong)
echo $a->instance; // you can't read directly variable number (wrong)
$a->getNumber(); // correct
