The 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
