You can use an anonymous class to return public variables from inside the class:
public function getPublicVars () {
$me = new class {
function getPublicVars($object) {
return get_object_vars($object);
}
};
return $me->getPublicVars($this);
}
Test script:
class Test {
protected $protected;
public $public;
private $private;
public function getAllVars () {
return call_user_func('get_object_vars', $this);
}
public function getPublicVars () {
$me = new class {
function getPublicVars($object) {
return get_object_vars($object);
}
};
return $me->getPublicVars($this);
}
}
$test = new Test();
print_r(get_object_vars($test)); // array("public" => NULL)
print_r($test->getAllVars()); // array("protected" => NULL, "public" => NULL, "private" => NULL)
print_r($test->getPublicVars()); // array("public" => NULL)
