PHP Traversal Object Properties Two ways

PHP Tutorial Traversal object Properties Two ways
/*
In this article we will provide you with two types of traversal object property methods, and illustrate the traversal object properties in PHP application.
*/
class Foo {
Private $a;
public $b = 1;
Public $c;
Private $d;
Static $e;

Public Function test () {
Var_dump (Get_object_vars ($this));
}
}

$test = new Foo;
Var_dump (Get_object_vars ($test));

$test->test ();

Method Two
class Foo {
Private $a;
public $b = 1;
Public $c = ' 111cn.net ';
Private $d;
Static $e;

Public Function test () {
Var_dump (Get_object_vars ($this));
}
}

$test = new Foo;
Var_dump (Get_object_vars ($test));

$test->test ();

The results are as follows:
Array (2) {
["B"]=>
Int (1)
["C"]=>
111cn.net
}
Array (4) {
["A"]=>
NULL
["B"]=>
Int (1)
["C"]=>
111cn.net
["D"]=>
NULL
}

/*
It's easy to see the results above to traverse object properties.
