1.2.764. Never Used Properties¶
Properties that are never used. They are defined in a class or a trait, but they never actually used.
Properties are considered used when they are used locally, in the same class as their definition, or in a parent class : a parent class is always included with the current class.
On the other hand, properties which are defined in a class, but only used in children classes is considered unused, since children may also avoid using it.
<?php
class foo {
public $usedProperty = 1;
// Never used anywhere
public $unusedProperty = 2;
function bar() {
// Used internally
++$this->usedProperty;
}
}
class foo2 extends foo {
function bar2() {
// Used in child class
++$this->usedProperty;
}
}
// Used externally
++$this->usedProperty;
?>
