    }

}

i need to seperate links and link labels into two seperate arrays. i followed several forums and made a code, but is getting error. i don't know about the find function used in the code

<?php $var = <<<EOD <html> <a href="sdfgs">sdfd</a> </html> EOD; $dom = new DOMDocument(); @$dom->loadHTML($var); $xpath = new DOMXPath($dom); foreach($xpath->query('//a') as $element) { $linklabel[] = $element->textContent; $link[] = $element->getAttribute("href"); } var_dump($linklabel); var_dump($link);
