get_object_vars (PHP 4 ) get_object_vars -- Returns an associative array of object properties Descriptionarray get_object_vars ( object obj)
This function returns an associative array of defined object properties for the specified object obj. Note: In versions prior to PHP 4.2.0, if the variables declared in the class of which the obj is an instance, have not been assigned a value, those will not be returned in the array. In versions after PHP 4.2.0, the key will be assigned with a NULL value.

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");
