$ HTML =的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 />';

有这样做的几种方法。至少告诉我们你卡在哪里。 – TNC 2015-01-21 11:21:29

我无法检索链接代码不工作？ – 2015-01-21 11:29:40

这会给你在你的HTML所有链接的链接：

$html = file_get_contents($urlcontent); 

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

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

print_r($links);

，如果你想在表中只有链接：

$html = file_get_contents($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);

我只想得到表格的链接 – 2015-01-21 11:42:52

@cleanguyFr我更新了我的答案 – Kiyan 2015-01-21 16:26:16

可以小写HTML后应用类似如下的一些代码串

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