How to print a nested array in php-CodePudding

I have this array

echo '<script type="application/ld json">';

$data = array(
    '@context' => 'https://schema.org',
    '@graph' => array(),
);

$data['@graph'][] = [
    "@type" => "ImageObject",
   
];

$data['@graph'][] = [
    "@type" => "BreadcrumbList",
    "itemListElement" => array(),
];

print_r(json_encode($data));

echo "</script>";

Now I want to add another array "itemListElement" inside the last $data['@graph'][] and print but don't know how to go about it.

am expecting

{
        "@type": "BreadcrumbList",
        "@id": "http:\/\/localhost\/#breadcrumb",
        "itemListElement": [{
            "@type": "ListItem",
            "position": "1",
            "item": {
                "@id": "http:\/\/localhost",
                "name": "Home"
            }
        }, {
            "@type": "ListItem",
            "position": "1",
            "item": {
                "@id": "link 2",
                "name": "Home"
            }
        }]
    }

You're referring to nested arrays.

echo '<script type="application/ld json">';

$data['@graph'][] = [
    '@type' => 'BreadcrumbList',
    '@id' => "http:\/\/localhost\/#breadcrumb",
    'itemListElement' => [
        [
            '@type' => 'ListItem',
            'position' => '1',
            'item' => [
                '@id' => "http:\/\/localhost",
                'name' => 'Home'
            ]
        ],
        [
            '@type' => 'ListItem',
            'position' => '2',
            'item' => [
                '@id' => 'link 2',
                'name' => 'Home'
            ]
        ]
    ]
];

print_r(json_encode($data));

echo "</script>";

Good luck on your test
