微打远程数据

微打APP的远程数据格式，官方没有资料，适合批量打印。

<?php
header('Content-Type: application/json; charset=utf-8');
$data = array(
    "col1" => array(
        array(
            "att1" => "红色",
            "att2" => 999
        ),
        array(
            "att1" => "蓝色",
            "att2" => 998
        ),
        array(
            "att1" => "黄色",
            "att2" => 997
        ),
        array(
            "att1" => "橙色",
            "att2" => 996
        )
    )
);
echo json_encode($data);
?>
