PHP - 析构函数可以访问任何方法或属性

Question

In php when using the destructor, does the code inside the destructor still have access to any methods and properties of the object?

Answer 1

Yes, you can access both methods and properties within a destructor, as demonstrated by this simple test-case:

class Foo {
    private $bar = 'member variable - ';
    function bar() {
        return 'function';
    }
    function __destruct() {
        echo $this->bar;
        echo $this->bar();
    }
}
$o = new Foo;
unset( $o);

Which prints:

member variable - function

See the PHP Docs on for deconstructors for more information, including their example of referencing a member variable from within the destructor.
