get_object_vars

Returns an associative array of object properties (PHP 4 )
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.

       $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);
   }

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