It’s time to use the symfony/dom-crawler method again. DOM Dafa is good, if you retreat from the rules, you will stay safe

composer.json

{ "require": { "symfony/css-selector": "^3.2", "symfony/dom-crawler": "^3.2" } }

a.php

 EOT; $dom = new Crawler(); $dom->addHtmlContent($str2, 'UTF-8'); $imgSrc = $dom->filter('td.imgp')->filter('img')->attr('src'); $productName = $dom->filter('td.propList')->filter('p.productName>a')->text(); $productProp6 = $dom->filter('td.propList')->filter('p.productProp6>.propValue')->text(); $productProp4 = $dom->filter('td.propList')->filter('p.productProp4>.propValue')->text(); var_dump($imgSrc); echo '
'; var_dump($productName); echo '
'; var_dump($productProp6); echo '
'; var_dump($productProp4); echo '
';

Output

DOM is naturally a better choice, but it’s not necessarily impossible to do it with regular methods.
