• PHP >= 8.1

How to use

There are two extractor realisation in this package: Balpom\LinksExtractor\SimpleExtractor and Balpom\LinksExtractor\Extractor

SimpleExtractor usage samples:

$css = 'div.cls1{background-image:url(/image-file-1.jpg);}
span.cls2{background-image:url(/image-file-2.png);}';

$extractor = new SimpleExtractor($css, 'text/css');
$linksProvider = $extractor->extract();
print_r($linksProvider->getLinks());

$html = '<a href="/page.html">ABC</a><a href="/page.html">XYZ</a>
<img src="/image-file-3.gif"><div>Else one <img src="/image-file-3.gif"></div>';

$extractor = new SimpleExtractor($html, 'text/html');
$linksProvider = $extractor->extract();
print_r($linksProvider->getLinks());

Extractor works also as a SimpleExtractor, but takes as a constructor argument an Psr\Http\Message\ResponseInterface object (https://www.php-fig.org/psr/psr-7/), not a string.
