Question

我有一个如图所示的显示表单，如果单击“添加jadwal”按钮会自动保存到列表中。

询问：单击按钮“ submit / simpan”后将如何列出数据数据表，成为数据json，如下所示？谢谢

 {
"mapel": [
  {
    "kelas": "1",
    "hari": "Senin",
  },
  {
    "kelas": "2",
    "hari": "Senin",
  },
]

}

如果您能够获取表示HTML的DOMDocument对象，则只需递归遍历它并构建所需的数据结构。

将HTML文档转换为DOMDocument应该很简单：

function html_to_obj($html) {
    $dom = new DOMDocument();
    $dom->loadHTML($html);
    return element_to_obj($dom->documentElement);
}

然后，简单遍历$ dom-> documentElement即可得到您所描述的结构，如下所示：

function element_to_obj($element) {
    $obj = array( "tag" => $element->tagName );
    foreach ($element->attributes as $attribute) {
        $obj[$attribute->name] = $attribute->value;
    }
    foreach ($element->childNodes as $subElement) {
        if ($subElement->nodeType == XML_TEXT_NODE) {
            $obj["html"] = $subElement->wholeText;
        }
        else {
            $obj["children"][] = element_to_obj($subElement);
        }
    }
    return $obj;
}

测试用例

<html lang="en">
    <head>
        <title> This is a test </title>
    </head>
    <body>
        <h1> Is this working? </h1>  
        <ul>
            <li> Yes </li>
            <li> No </li>
        </ul>
    </body>
</html>



header("Content-Type: text/plain");
echo json_encode(html_to_obj($html), JSON_PRETTY_PRINT);

输出

{
    "tag": "html",
    "lang": "en",
    "children": [
        {
            "tag": "head",
            "children": [
                {
                    "tag": "title",
                    "html": " This is a test "
                }
            ]
        },
        {
            "tag": "body",
            "html": "  \n        ",
            "children": [
                {
                    "tag": "h1",
                    "html": " Is this working? "
                },
                {
                    "tag": "ul",
                    "children": [
                        {
                            "tag": "li",
                            "html": " Yes "
                        },
                        {
                            "tag": "li",
                            "html": " No "
                        }
                    ],
                    "html": "\n        "
                }
            ]
        }
    ]
}
