Answer 1

Quick hack:

// assuming $var is a multidimensional array
$obj = json_decode (json_encode ($var), FALSE);

Not pretty, but works.

function object_to_array($data)
{
    if (is_array($data) || is_object($data))
    {
        $result = array();
        foreach ($data as $key => $value)
        {
            $result[$key] = object_to_array($value);
        }
        return $result;
    }
    return $data;
}

function array_to_object($data)
{
    if (is_array($data) || is_object($data))
    {
        $result= new stdClass();
        foreach ($data as $key => $value)
        {
            $result->$key = array_to_object($value);
        }
        return $result;
    }
    return $data;
}

Inspired by all these codes, i tried to create a enhanced version with support to: specific class name, avoid constructor method, 'beans' pattern and strict mode (set only existing properties):

    class Util {

static function arrayToObject($array, $class = 'stdClass', $strict = false) {
        if (!is_array($array)) {
            return $array;
        }

        //create an instance of an class without calling class's constructor
        $object = unserialize(
                sprintf(
                        'O:%d:"%s":0:{}', strlen($class), $class
                )
        );

        if (is_array($array) && count($array) > 0) {
            foreach ($array as $name => $value) {
                $name = strtolower(trim($name));
                if (!empty($name)) {

                    if(method_exists($object, 'set'.$name)){
                        $object->{'set'.$name}(Util::arrayToObject($value));
                    }else{
                        if(($strict)){

                            if(property_exists($class, $name)){

                                $object->$name = Util::arrayToObject($value); 

                            }

                        }else{
                            $object->$name = Util::arrayToObject($value); 
                        }

                    }

                }
            }
            return $object;
        } else {
            return FALSE;
        }
        }
}

Code

This function works as same as json_decode(json_encode($arr), false).

function arrayToObject(array $arr)
{
    $flat = array_keys($arr) === range(0, count($arr) - 1);
    $out = $flat ? [] : new \stdClass();

    foreach ($arr as $key => $value) {
        $temp = is_array($value) ? $this->arrayToObject($value) : $value;

        if ($flat) {
            $out[] = $temp;
        } else {
            $out->{$key} = $temp;
        }
    }

    return $out;
}

Testing

Test 1: Flat array

$arr = ["a", "b", "c"];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));

Output:

array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
)
array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
)

Test 2: Array of objects

$arr = [["a" => 1], ["a" => 1], ["a" => 1]];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));

Output:

array(
    0 => stdClass::__set_state(array('a' => 1,)),
    1 => stdClass::__set_state(array('a' => 1,)),
    2 => stdClass::__set_state(array('a' => 1,)),
)
array(
    0 => stdClass::__set_state(array('a' => 1,)),
    1 => stdClass::__set_state(array('a' => 1,)),
    2 => stdClass::__set_state(array('a' => 1,)),
)

Test 3: Object

$arr = ["a" => 1];
var_export(json_decode($arr));
var_export($this->arrayToObject($arr));

Output:

stdClass::__set_state(array('a' => 1,))
stdClass::__set_state(array('a' => 1,))

Answer 5

i have done it with quite simple way,

    $list_years         = array();
    $object             = new stdClass();

    $object->year_id   = 1 ;
    $object->year_name = 2001 ;
    $list_years[]       = $object;

Answer 6

You could also do this by adding (object) on left of variable to create a new object.

<?php
$a = Array
    ( 'status' => " text" );
var_dump($a);
$b = (object)$a;
var_dump($b);
var_dump($b->status);
