How to push JSONObject to JSONArray in PHP

Question

I want to push a new JSONObject into my existing JSONArray.

This below code explaining better, what i want to do:

[
    [
        {
            "text":"Row 1 Column 1"
        },
        // My mine is add anthor JSONObject in here.
    ],
    [
        {    
            "text":"Row 2 Column 1"
        },
        {
            "text":"Row 2 Column 2"
        }
    ]
]

$json= '
    [
        [
            {
                "text":"Row 1 Column 1"
            }
        ],
        [
            {
                "text":"Row 2 Column 1"
            },
            {
                "text":"Row 2 Column 2"
            }
        ]
    ]
    ';

    $p = json_decode($j);

    $p[0][]=["text"=>"Row 1 Column 2"];

    print_r(json_encode($p)); // print_r for debug, $result = json_encode($p)

You need to first handle your data in a array and then convert it to a json array

I would do it like this :

$array = [
    [
        [
            "text" => "Row 1 Column 1"
        ]
    ],
    [
        [
            "text" => "Row 2 Column 1"
        ],
        [
            "text" => "Row 2 Column 2"
        ]
    ]
];

// a element in the first sub array
$array[0][] = [
    "text" => "Row 1 Column 2"
];

Does that help ?
