PHP Object to Array

PHP Object To Array

Convert simple Object to array is easy, however to convert a complex Object is tricky. You need to write a custom function to do the convertion recursively from Object to array. Please check the example on how to do it.

Example 1: Convert a simple object to an array

<?php

$object = new stdClass();
$object->name = "Bob Markina";
$object->age = 24;

$my_array = (array) $object;

print_r($my_array);
?>

Output

Array ( [name] => Bob Markina [age] => 24 )

PHP Function to convert object to an array recursively

For complex object, you need to use this function to convert object to an array recursively.

<?php

function objectToArray($d) {
	if (is_object($d)) {
		// Gets the properties of the object
		$d = get_object_vars($d);
	}

	if (is_array($d)) {
		return array_map(__FUNCTION__, $d);
	} else {
		// Return array
		return $d;
	}
}
?>

Example 2

Without using the custom function, you will not convert all objects to array correctly.

<?php
require_once 'myfunction.php';

$employee_obj = new stdClass();
$employee_obj->name = 'Jamy Jo';
$employee_obj->age = 58;
$employee_obj->address->street = '240 Lake Rd';
$employee_obj->address->apartment = '240';
$employee_obj->address->state = 'Tx';
$employee_obj->address->city = 'Houston';
$employee_obj->address->zip = '77300';
$employee_obj->role = 'PHP Developer';

// convert to an array use custom function
$my_array = objectToArray($employee_obj);

print_r($my_array);

?>

Output

Array
(
    [name] => Jamy Jo
    [age] => 58
    [address] => Array
        (
            [street] => 240 Lake Rd
            [apartment] => 240
            [state] => Tx
            [city] => Houston
            [zip] => 77300
        )

    [role] => PHP Developer
)
