您可以像这样创建$data和编码 json

<?php
$data = array
(
    "Maths" => array(
        array(
            "Name" => "ramesh", // First element
            "Marks" => 67,
            "age" => 23
        ), array(
            "Name" => "mayur", // Second element
            "Marks" => 65,
            "age" => 21
        )
    ),
    "Science" => array(
        array(
            "Name" => "ram", // First Element
            "Marks" => 56,
            "age" => 27
        ),
        array(
            "Name" => "Santosh", // Second Element
            "Marks" => 78,
            "age" => 41
        )
    )
);
echo json_encode($data);
