使用PHP从网站保存HTML标记<td>数据

Question

I am trying to save the song title from the URL: https://onlineradiobox.com/us/977todayshits/playlist

I used the below code to fetch data

$html = file_get_contents("https://onlineradiobox.com/us/977todayshits/playlist");
    $matches = array();
    $output = preg_match_all('/<table class="tablelist-schedule" role="log">(.*?)<\/table>/s', $html, $matches,PREG_SET_ORDER );
    echo "<pre>";
    print_r($matches);
    echo "</pre>";

The result from the above Code:

Live    Mark Ronson - Nothing Breaks Like a Heart (feat. Miley Cyrus)
10:41   Camila Cabello - Consequences
10:38   Imagine Dragons - It's Time
10:34   Panic! at the Disco - High Hopes
10:31   Selena Gomez - Hands to Myself

This code gets the data but I don't know how will I save the 2nd td tag value in a table. It is not necessary that 2nd td will be a link when it is not linked then there is no class defined in td tag.

As @Denis V said, don't use RegEx to parse html/xml content, use a proper lib for this, like LibXML...

Example:

$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML(file_get_contents('https://onlineradiobox.com/us/977todayshits/playlist'));

$xPath = new DOMXPath($dom);

$nodes = $xPath->query('//table[@class="tablelist-schedule"]/tbody/tr/td[2]');

foreach ($nodes as $node) {
    echo $node->textContent . "
";
}

Prints...

Pitbull - Time Of Our Lives (feat. Ne Yo)

Ellie Goulding - Close to Me (x Diplo feat. Swae Lee)

Post Malone & Swae Lee - Sunflower

Why Don't We - 8 Letters

NF - Lie

... list too long...
