但如果我这样做echo json_encode($data);
，它不会给我这种格式......（它给我空白）
[{"text":"","spot":"","ball":"","togo":"0","type":"","drive":""},{"text":"","spot":"","ball":"","togo":"0","type":"","drive":""},{"text":"","spot":"","ball":"","togo":"0","type":"","drive":""},{"text":"","spot":"","ball":"","togo":"0","type":"","drive":""},{"text":"","spot":"","ball":"","togo":"0","type":"","drive":""}]
$data 未通过 json 编码的可能原因是什么？
这是来自 print_r($data);
