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.

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 printout of the above program will be:

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