In PHP, you can use the get_object_vars() function to convert the object into an array.

get_object_vars — Returns an associative array composed of object properties. Syntax format:

get_object_vars ( object $obj ) : array

Returns an associative array composed of attributes defined in the object specified by obj.

Note:

In versions prior to PHP 4.2.0, if variables declared in the obj object instance are not assigned a value, they will not be in the returned array . After PHP 4.2.0, these variables will be assigned null values as key names.

Example:

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)); ?>

Output:

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