# get_object_vars

(PHP 4 )

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`. If 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.

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:

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

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