Virtual Property¶
A virtual property is a class property, whose property hooks don’t use the value. The virtual property has no need for actual storage, and relies on other means to provide the value. In effect, they rely on the property hooks get and set to access the value. They also rely on other properties, global variables or data generators to provide a value.
A virtual property cannot be static, as property hooks are not supported for this type of properties.
<?php
class Counter {
private $count = 1;
// $next is a virtual property : it doesn't rely on $this->next;
public $next {
get => $this->count + 1 + rand(0, 10);
set {}
}
}
?>
