PHP stdClass to Array and Array to stdClass – stdClass Object

Updated by on Jun 17, 2011 in Featured, PHP, Programming | 11 comments

I think every PHP coders have come accross Arrays and stdClass Objects (belongs to PHP Predefined Classes). Sometimes it’s very useful convert Objects to Arrays and Arrays to Objects. This is easy if arrays and objects are one-dimensional, but might be little tricky if using multidimensional arrays and objects.

This post defines two ultra simple recursive function to convert multidimensional Objects to Arrays and multidimensional Arrays to Objects.

Function to Convert stdClass Objects to Multidimensional Arrays

<?php
 
	function objectToArray($d) {
		if (is_object($d)) {
			// Gets the properties of the given object
			// with get_object_vars function
			$d = get_object_vars($d);
		}
 
		if (is_array($d)) {
			/*
			* Return array converted to object
			* Using __FUNCTION__ (Magic constant)
			* for recursive call
			*/
			return array_map(__FUNCTION__, $d);
		}
		else {
			// Return array
			return $d;
		}
	}
 
?>

Function to Convert Multidimensional Arrays to stdClass Objects

<?php
 
	function arrayToObject($d) {
		if (is_array($d)) {
			/*
			* Return array converted to object
			* Using __FUNCTION__ (Magic constant)
			* for recursive call
			*/
			return (object) array_map(__FUNCTION__, $d);
		}
		else {
			// Return object
			return $d;
		}
	}
 
?>

Function usage

	// Create new stdClass Object
	$init = new stdClass;
 
	// Add some test data
	$init->foo = "Test data";
	$init->bar = new stdClass;
	$init->bar->baaz = "Testing";
	$init->bar->fooz = new stdClass;
	$init->bar->fooz->baz = "Testing again";
	$init->foox = "Just test";
 
	// Convert array to object and then object back to array
	$array = objectToArray($init);
	$object = arrayToObject($array);
 
	// Print objects and array
	print_r($init);
	echo "\n";
	print_r($array);
	echo "\n";
	print_r($object);

Test output:

stdClass Object
(
    [foo] => Test data
    [bar] => stdClass Object
        (
            [baaz] => Testing
            [fooz] => stdClass Object
                (
                    [baz] => Testing again
                )

        )

    [foox] => Just test
)

Array
(
    [foo] => Test data
    [bar] => Array
        (
            [baaz] => Testing
            [fooz] => Array
                (
                    [baz] => Testing again
                )

        )

    [foox] => Just test
)

stdClass Object
(
    [foo] => Test data
    [bar] => stdClass Object
        (
            [baaz] => Testing
            [fooz] => stdClass Object
                (
                    [baz] => Testing again
                )

        )

    [foox] => Just test
)

    Hi, in reference to what your using it for La5, you should just pass true as the second variable of json_decode to get it to return an associative array

    eg:

    $json =’{ “blah”:”bleh”}’;
    json_decode($json, TRUE);
