Question

is a way to get first value of image src without foreach?

$doc->loadHTML($description);

foreach ($doc->getElementsByTagName('img') as $image) {
    echo $image->getAttribute('src');
}

this is not working $doc->getElementsByTagName('img')->item(0)->nodeValue);

Answer 1

This should work:

echo $doc->getElementsByTagName('img')->item(0)->getAttribute('src');
