Example 1. Use of get_object_vars()

<?php
class Point2D {
    var $x, $y;
    var $label;

    function Point2D($x, $y) {
        $this->x = $x;
        $this->y = $y;
    }

    function setLabel($label) {
        $this->label = $label;
    }

    function getPoint() {
        return array("x" => $this->x,
                     "y" => $this->y,
                     "label" => $this->label);
    }
}

// "$label" is declared but not defined
$p1 = new Point2D(1.233, 3.445);
print_r(get_object_vars($p1));

$p1->setLabel("point #1");
print_r(get_object_vars($p1));

?>
The printout of the above program will be:

 (
     [x] => 1.233
     [y] => 3.445
 )
