需要帮助从PHP中获取JSON的一部分

Question

Need help in getting some part from my json. I already search for this on website and google but didn't find good example. This my json :

{
"_doc": "lusti",
"id": 123456,
"title": "Dokumenku dari Json",
"parsel": {
    "_doc": "parsel",
    "id": 3256,
    "doc_type": "Word",
    "title": "bendahara12.doc",
    "download_link": {
        "Word": [
            {
                "label": "doc1",
                "file": "http://example.com/file_doc1.doc"
            },
            {
                "label": "doc2",
                "file": "http://example.com/file_doc2.doc"
            },
            {
                "label": "doc3",
                "file": "http://example.com/file_doc3.doc"
            },
            {
                "label": "doc4",
                "file": "http://example.com/file_doc4.doc"
            }
        ]
    }
}

and this my table :

<td class="tg-baqh"><a class="btn" href="<?php echo $json['???']; ?>">Doc 1</a></td>
<td class="tg-baqh"><a class="btn" href="<?php echo $json['???']; ?>">Doc 2</a></td>
<td class="tg-baqh"><a class="btn" href="<?php echo $json['???']; ?>">Doc 3</a></td>
<td class="tg-baqh"><a class="btn" href="<?php echo $json['???']; ?>">Doc 4</a></td>

i need get link for my download button. look like :

<td class="tg-baqh"><a class="btn" href="http://example.com/file_doc1.doc">Doc 1</a></td>
<td class="tg-baqh"><a class="btn" href="http://example.com/file_doc2.doc">Doc 2</a></td>

<td class="tg-baqh"><a class="btn" href="http://example.com/file_doc4.doc">Doc 4</a></td>

You need to parse JSON data using json_decode():

$array = json_decode($json_string,true);

Now you can get data in array format. Now you need to write foreach loop for retrieve download link data.Like below:

$download_link = $array['parsel']['download_link']['Word'];
foreach($download_link as $key=>$val){
    echo '<td class="tg-baqh"><a class="btn" href="' . $val['file'] . '">'. $val['label'] .'</a></td>';
}
