Sorry for the duplicate question, but I am not able to render json_decod multi-dimensional array in template file.
I also tried using ArrayList and ArrayData but it is working with a single array not with multi-dimensional array.
Any other method is there for the same?

ArrayList/ArrayData works fine, but you'll have to specify iterations as a list.

public function testLoop() {
	return ArrayList::create([
		1 => ['foo'=>['bar'=>'hello']],
		2 => ['foo'=>['bar'=>'world']],
	]);
}
<% loop $testLoop %>
$foo.bar
<% end_loop %>

public function testWith() {
	return ArrayData::create([
		'foo'=>['bar'=>'hello']
	]);
}
<% with $testWith %>
$foo.bar
<% end_with %>

Thanks @Devlin for this working code, but I am little confused with my json data.

$jsonData = json_decode($response->getBody(), true);    
    
 $output = ArrayList::create([
     $jsonData
 ]);

When I print this I got result like

ArrayList Object
(
    [items:protected] => Array
        (
            [0] => Array
                (
                    [Page] => 1
                    [PageCount] => 1
                    [MinPrice] => 46
                    [MaxPrice] => 187
                    [RecordCount] => 3
                    [SearchResults] => Array
                        (
                            [0] => Array
                                (
                                    [Hotel] => Array
                                        (
                                            [Address] => ZZZZZZZZ

Your json_decode array looks something like this:

$jsonData = [
	'MinPrice' => 46,
	'MaxPrice' => 187,
	'SearchResults' => [
		0 => [
			'Hotel' => [
				'Address' => 'ZZZZZZZZ',
				'Id' => 52,
				'Photos' => [
					0 => [
						'Id' => 0,
						'Source' => 'ZZZZZZZZ',
					]
				],
			],
			'Price' => 46,
		],
		1 => [
			'Hotel' => [
				'Address' => 'ZZZZZZZZ',
				'Id' => 47,
				'Photos' => [
					0 => [
						'Id' => 0,
						'Source' => 'ZZZZZZZZ',
					]
				],
			],
			'Price' => 177.65,
		]
	]
];

To use it in a template it should look something like this:

public function testList() {
	return ArrayList::create([
		0 => [
			'MinPrice' => 46,
			'MaxPrice' => 187,
			'SearchResults' => ArrayList::create([
				0 => [
					'Hotel' => [
						'Address' => 'ZZZZZZZZ',
						'Id' => 52,
						'Photos' => ArrayList::create([
							0 => [
								'Id' => 0,
								'Source' => 'ZZZZZZZZ',
							]
						]),
					],
					'Price' => 46,
				],
				1 => [
					'Hotel' => [
						'Address' => 'ZZZZZZZZ',
						'Id' => 47,
						'Photos' => ArrayList::create([
							0 => [
								'Id' => 0,
								'Source' => 'ZZZZZZZZ',
							]
						]),
					],
					'Price' => 177.65,
				]
			])
		]
	]);
}
<% loop $testList %>
	$MinPrice<br>
	$MaxPrice<br>
	<% loop $SearchResults %>
		$Hotel.Address<br>
		$Hotel.Id<br>
		<% loop $Hotel.Photos %>
			$Id<br>
			$Source<br>
		<% end_loop %>
		$Price<br>
	<% end_loop %>
<% end_loop %>

So you have to parse $jsonData like:

public function testList() {
	$jsonData = []; // see above
	$jsonData = Convert::raw2xml($jsonData); // because all input data is evil

	$myResults = ArrayList::create();
	foreach($jsonData['SearchResults'] as $searchResult) {
		$myResult = $searchResult;
		$myResult['Hotel']['Photos'] = ArrayList::create();
		foreach($searchResult['Hotel']['Photos'] as $photo) {
			$myResult['Hotel']['Photos']->push($photo);
		}
		$myResults->push($myResult);
	}
	return ArrayList::create([
		0 => [
			'MinPrice' => $jsonData['MinPrice'],
			'MaxPrice' => $jsonData['MaxPrice'],
			'SearchResults' => $myResults,
		]
	]);
}
