# get_object_vars

(PHP 4, PHP 5)

get_object_vars -- Returns an associative array of object properties

## Description

array 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.

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 above example will output:
    Array
     (
         [x] => 1.233
         [y] => 3.445
         [label] =>
     )

     Array
     (
         [x] => 1.233
         [y] => 3.445
         [label] => point #1
     )
