This function now returns NULL if the
object isn't an object.
|
| prior to 5.3.0 |
If the object isn't an object, then
get_object_vars() would return FALSE
|
| prior to 4.2.0 |
If the variables declared in the class of which the
object is an instance, have not been assigned a
value, those will not be returned in the array

Example #2 Use of get_object_vars()
<?php
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));
