Как преобразовать HTML-таблицу в JSON в PHP

Я пытаюсь преобразовать некоторый html в массив, а затем в строку json.

Я разрабатываю на основе этой ссылки: https://www.codeproject.com/Tips/1074174/Simple-Way-to-Convert-HTML-Table-Data-into-PHP-Arr

Это основная таблица / html, из которой я хочу преобразовать ее в JSON.

<table class = "table-list table table-responsive table-striped">
<thead>
    <tr>
        <th class = "coll-1 name">name</th>
        <th class = "coll-2">height</th>
        <th class = "coll-3">weight</th>
        <th class = "coll-date">date</th>
        <th class = "coll-4"><span class = "info">info</span></th>
        <th class = "coll-5">country</th>
    </tr>
</thead>
<tbody>
<tr>
    <td class = "coll-1 name">
        <a href = "/username/Jhon Doe/" class = "icon"><i class = "flaticon-user"></i></a>
        <a href = "/username/Jhon Doe/">Jhon Doe</a>
    </td>
    <td class = "coll-2 height">45</td>
    <td class = "coll-3 weight">50</td>
    <td class = "coll-date">9am May. 16th</td>
    <td class = "coll-4 size mob-info">abcd</td>
    <td class = "coll-5 country"><a href = "/country/CA/">CA</a></td>
</tr>
<tr>
    <td class = "coll-1 name">
        <a href = "/username/Kasim Shk/" class = "icon"><i class = "flaticon-user"></i></a>
        <a href = "/username/Kasim Shk/">Kasim Shk</a>
    </td>
    <td class = "coll-2 height">33</td>
    <td class = "coll-3 weight">54</td>
    <td class = "coll-date">Mar. 14th '18</td>
    <td class = "coll-4 size mob-info">ijkl</td>
    <td class = "coll-5 country"><a href = "/country/UAE/">UAE</a></td>
</tr>
</tbody>
</table>

Я хочу, чтобы вывод json был таким:

[
    {   
        "user_link": "/username/Jhon Doe/",
        "name": "Jhon Doe",
        "height": "45",
        "weight": "50",
        "date": "Apr. 01st '18",
        "info": "abcd",
        "country": "CA"
    },
    {   
        "user_link": "/username/Kasim Shk/",
        "name": "Kasim Shk",
        "height": "33",
        "weight": "54",
        "date": "Mar. 14th '18",
        "info": "ijkl",
        "country": "UAE"
    }
]

Это то, что я пробовал в PHP :(

Однако это не может получить ссылку пользователя, и имя в JSON неверно.

(Таблица HTML такая же, как и выше @ http://rudraproduction.in/htmltable.php)

header("Access-Control-Allow-Origin: *");                                                                            
header('Content-Type: application/json');
error_reporting(E_ERROR | E_PARSE);
$time_start = microtime(true);

$All = [];

$link       = 'http://rudraproduction.in/htmltable.php';
$jsonData   = file_get_contents($link);

//echo $jsonData;

$dom = new DOMDocument;
$dom->loadHTML($jsonData);

$tables = $dom->getElementsByTagName('table');
$tr     = $dom->getElementsByTagName('tr'); 

foreach ($tr as $element1) {        
    for ($i = 0; $i < count($element1); $i++) {

        //Not able to fetch the user's link :(

        $link       = $element1->getElementsByTagName('td')->item(0)->getElementsByTagName('a');    // To fetch user link
        $name       = $element1->getElementsByTagName('td')->item(0)->textContent;                  // To fetch name
        $height     = $element1->getElementsByTagName('td')->item(1)->textContent;                  // To fetch height
        $weight     = $element1->getElementsByTagName('td')->item(2)->textContent;                  // To fetch weight
        $date       = $element1->getElementsByTagName('td')->item(3)->textContent;                  // To fetch date
        $info       = $element1->getElementsByTagName('td')->item(4)->textContent;                  // To fetch info
        $country    = $element1->getElementsByTagName('td')->item(5)->textContent;                  // To fetch country

        array_push($All, array(
            "user_link" => $link,
            "name"      => $name,
            "height"    => $height,
            "weight"    => $weight,
            "date"      => $date,
            "info"      => $info,
            "country"   => $country
        ));
    }
}

echo json_encode($All, JSON_PRETTY_PRINT);

Вывод моего PHP-кода:

[
    {
        "user_link": "http://rudraproduction.in/htmltable.php",
        "name": null,
        "height": null,
        "weight": null,
        "date": null,
        "info": null,
        "country": null
    },
    {
        "user_link": "http://rudraproduction.in/htmltable.php",
        "name": "\r\n\t\t\r\n\t\tJhon Doe\r\n\t",
        "height": "45",
        "weight": "50",
        "date": "9am May. 16th",
        "info": "abcd",
        "country": "CA"
    },
    {
        "user_link": "http://rudraproduction.in/htmltable.php",
        "name": "\r\n\t\t\r\n\t\tKasim Shk\r\n\t",
        "height": "33",
        "weight": "54",
        "date": "Mar. 14th '18",
        "info": "ijkl",
        "country": "UAE"
    }
]
