捕获没有图像链接的PHP链接

Question

$url = 'http://www.test.com/';
$dom = new DOMDocument;
@$dom->loadHTMLFile($url);

$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {

I am currently using the above script the capture links on a page, however what I found was there are always duplicate links. On the page, there is a picture which is linked, followed by a text link which goes to the same link. Is there an easy way to capture just the text link, not the image link?

Answer 1

As I was saying, I might take the approach of cleaning up the dupes in my result set. Not sure on what you are scraping but what if the link is only used with an image?

You could even count the occurrences.

$url = 'http://www.test.com/';
$dom = new DOMDocument;
@$dom->loadHTMLFile($url);

$links = $dom->getElementsByTagName('a');
$distinctLinks = [];
foreach ($links as $link) {
    $distinctLinks[$link] = (int) $distinctLinks[$link] + 1;
}
