$ html = file_get_contents（$ urlcontent）;

$dom = new DOMDocument();
@$dom->loadHTML($html);

// grab all the on the page
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//tr");



for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);
$url = $href->getAttribute('href');

echo $url.'<br />';
}

如何从表中获取链接并使用php

将其保存在file.txt中

我只想获得表格的链接

Answer 1

这将为您提供HTML中的所有链接：

$html = file_get_contents($urlcontent);

$dom = new DOMDocument();
@$dom->loadHTML($html);

$links = array();
foreach($dom->getElementsByTagName('a') as $node)
    $links[] = $node->getAttribute('href');

print_r($links);

如果你想只获得表格中的链接：

$html = file_get_contents($urlcontent);

$dom = new DOMDocument();
@$dom->loadHTML($html);

$links = array();
foreach($dom->getElementsByTagName('table') as $table)
    foreach($table->getElementsByTagName('a') as $node){
        $href = $node->getAttribute('href');
        if(!in_array($href, $links))
            $links[] = $href;
    }

print_r($links);

Answer 2

您可以在小写html之后应用以下代码作为字符串

$matches = array();
preg_match('/<a\s[^>]*href=\"([^\"]*)\"/', $url, $matches);

从表php获取链接
