从html代码中获取每个tr类元素

Question

我建立了这段代码：

    $url_athlete = 'https://www.sports-reference.com/olympics/athletes/tr/giangiorgio-count-trissino-1.html';
                  $html3 = file_get_html($url_athlete,true);

          $results = array();

                    foreach($html3->getElementsById('results') as $tag3){

                     foreach($tag3->getElementsByTagName('tr') as $tag4){

                       echo $tag4->plaintext . "\n";

}
}

感谢这段代码，如果我打印出获得此输出的tag4变量：

Games   Age   City   Sport   Event   Team   NOC   Rank   Medal
    1900 Summer    22    Paris    Equestrianism    Mixed Long Jump    Italy    ITA    2    Silver
    1900 Summer    22    Paris    Equestrianism    Mixed High Jump    Italy    ITA    1T     Gold
    1900 Summer    22    Paris    Equestrianism    Mixed High Jump    Italy    ITA    4

好吧，我尝试过多种方式但没有结果，我想从tag4获取这些值并将它们分配给变量，即：

$year --> 1900
$season --> Summer
$Sport --> Equestrianism
$gender -> Mixed
$event --> Long Jump
$rank --> 2
$medal --> silver

之后我会将这些值插入表中。 然后第二行：

$year --> 1900
    $season --> Summer
    $Sport --> Equestrianism
    $gender -> Mixed
    $event --> High Jump
    $rank --> 1T
    $medal --> gold

然后插入，依此类推最后一行。 我该怎么办？
